String Manipulation in java

In example, Test class has a main method and local string variable with few string manipulation i.e length of string, character at given position and string comparison.

 public class Test1  
 {  
      public static void main(String args[])  
      {  
           String result1="hello java";  
           int result2=result1.length()%3;  
           char result3=result1.charAt(3);  
           String result4="result1"+"result1";  
           System.out.println(result1.equals("hello java"));  
           System.out.println(result2);  
           System.out.println(result3);  
           System.out.println(result4);  
           System.out.println(result1.lastIndexOf('w'));  
      }  
 }
