how to compare a string in java code example

Example 1: java how to compare strings

System.out.println("hey".equals("hey")); //prints true

/*
	always use .equals() instead of ==,
    because == does the compare the string content but
    loosely where the string is stored in.
*/

Example 2: string compare java ==

// These two have the same value
new String("test").equals("test") // --> true 

// ... but they are not the same object
new String("test") == "test" // --> false 

// ... neither are these
new String("test") == new String("test") // --> false

Example 3: Java compare two strings

// compare two strings in java .equals() method
public class EqualOperatorDemo
{
   public static void main(String[] args)

      String str1 = new String("helloworld");
      String str2 = new String("helloworld");
      System.out.println(str1 == str2);
      System.out.println(str1.equals(str2));
   }
