How to remember Username and Password when pull or push Project with Git

Remember username and password when pull or push project 

In this tutorial I will share how to remember username and password when pull or push by working with git , also I will share how to avoid conflict lines  when developers are working at the same file in project.

To git remember username and password when pull or push

1) Go to your project folder
2) Right click in your project
3) Select Git Bash
4) Type: git config credential.helper store
5) Enter : your username and password

Then when pull or push git next time it will remember your username and password automatically.

Sometime developers are working at the same file ,one developer committed his/her task first ,and next developer do the same lines and the same file when pull it will conflict lines that required developer merge or resolved  that file or revert the previous file. To avoid conflict lines at the same file , here is step by step to avoid conflict line at the same file.

1) Commit your task (do not click button Push , just only commit )
2) Right click your project folder or your repository project
3) Stash Save
4) pull
5) stash pop
6) push

when push your project git will merge your code and line automatically.

Comparator Date - Java

In this tutorial you will know how to compare Date  in java .
In this section we will do step by step
1. Comparator Date in Java
2. Comparator by using method after(), before() and equal()

public boolean after(Date date);
public boolean  before(Date date)
public boolean equal(Object o);

See Example1;

import java.util.Date;

public class Details {
       public static void main(String[] args) {
Date today = new Date();
Date myDate = new Date(today.getYear(),today.getMonth()-1,today.getDay());
getCompareDate(today, myDate);
}
public static void getCompareDate(Date today, Date myDate){
System.out.println("method Comparator > My Date is : "+myDate);  
    System.out.println("method Comparator Today Date is : "+today);
    if (today.compareTo(myDate)<0){
        System.out.println(" method Comparator Today Date is Lesser than my Date");
    }
    else if (today.compareTo(myDate)>0){
        System.out.println(" method Comparator Today Date is Greater than my date");
    }  
    else{
        System.out.println("Both Dates are equal");
    }

}

//result:
method Comparator > My Date is : Mon Feb 01 00:00:00 ICT 2016
method Comparator Today Date is : Mon Mar 14 23:52:02 ICT 2016
 method Comparator Today Date is Greater than my date


Example2: method after(), before(), equal();

import java.util.Date;

public class Details {
public static void main(String[] args) {
Date today = new Date();
Date myDate = new Date(today.getYear(),today.getMonth()-1,today.getDay());
getDateComapreBeforeAndAfter(today, myDate);
}

private static void getDateComapreBeforeAndAfter(Date today, Date myDate){
//After() or before() or equal() method want to know today > myDate ? and it return boolean true or false
System.out.println("Date method compare Before : "+today.before(myDate));
System.out.println("Date method compare After : "+today.after(myDate));
System.out.println("Date method compare equal : "+today.equals(myDate));
}
}

result :

Date method compare Before : false
Date method compare After : true
Date method compare equal : false

Vector to Array - Java

In this tutorial we will convert vector to Array in java  and to convert vector to array we used method
Vector.toArray();

Syntax:  public Object [] toArray();

See Example:


import java.util.Arrays;
import java.util.HashSet;
import java.util.Set;

public class Example {

public static void main(String args[]) {
//console method 
vectorToArray();

}
//declare method to get Vector 
public static void vectorToArray(){
//Declare String[] 
String elements[] = { "Book1", "Book2", "Book3", "Book4", "Book5" };
// convert String[] to List
Set set  =  new HashSet(Arrays.asList(elements));
String[] strObj = new String[set.size()];
strObj = (String[]) set.toArray(strObj);
for (int i = 0; i < strObj.length; i++) {
        System.out.println(strObj[i]);
     }
     System.out.println(set);
}

}

//result :

Book5
Book3
Book4
Book1
Book2
[Book5, Book3, Book4, Book1, Book2]

Vector Remove Object - Java

In this we will remove Object from Vecctor by using method remove()

Syntax : public boolean remove(Object o);

See Example:

import java.util.Vector;

public class Example {

public static void main(String args[]) {
Vector vector = new Vector(3);
vector.add(3);
vector.add(1);
vector.add(2);
System.out.println("Vector before remove element: "+vector);
System.out.println("Removed element from vector: "+vector.remove((Integer)1));
System.out.println("Vector after remove element: "+vector);
 
}

}

//result :

Vector before remove element: [3, 1, 2]
Removed element from vector: true
Vector after remove element: [3, 2]

Vector Remove Element - Java

To remove element from Vector we will use method

See Example:

import java.util.Iterator;
import java.util.Vector;

public class Example {

public static void main(String args[]) {
   
     Vector<String> vec = addVector();
 
}
//declare method to get Vector 
public static Vector<String> addVector(){
/* Vector of initial */
 Vector<String> vectors = new Vector<String>();
 /* Adding elements to a vector*/
 vectors.addElement("Item1");
 vectors.addElement("Item2");
 vectors.addElement("Item3");
 vectors.addElement("Item4");
 vectors.addElement("Item5");
 System.out.println("Vector elements : "+vectors);
 System.out.println("Vector Size Before Remove : "+vectors.size());
 //remove first element "Item1" of index zero
 System.out.println("Removed element: "+vectors.remove(0));
 System.out.println("Vector Size after Remove : "+vectors.size());

 return vectors;

}

}

//result :

Vector elements : [Item1, Item2, Item3, Item4, Item5]
Vector Size Before Remove : 5
Removed element: Item1
Vector Size after Remove : 4

Vector Iterator - java

In this tutorial we will loop or Iterator  vector .

See Example:


import java.util.Iterator;
import java.util.Vector;

public class Example {

public static void main(String args[]) {
   
     Vector<String> vec = addVector();
     System.out.println("Elements Vector : "+vec);
     Iterator iterator = vec.iterator();
     while(iterator.hasNext()){
         System.out.println("Vector Iterator  : "+iterator.next());
       }
  }
//declare method to get Vector 
public static Vector<String> addVector(){
/* Vector of initial  */
 Vector<String> vectors = new Vector<String>();
 /* Adding elements to a vector*/
 vectors.addElement("Item1");
 vectors.addElement("Item2");
 vectors.addElement("Item3");
 vectors.addElement("Item4");
 vectors.addElement("Item5");
 return vectors;

}

}

// result :

Elements Vector : [Item1, Item2, Item3, Item4, Item5]
Vector Iterator  : Item1
Vector Iterator  : Item2
Vector Iterator  : Item3
Vector Iterator  : Item4
Vector Iterator  : Item5
