Conversion of character to String not working

Question

String s="rahul".substring(0, 1);
  s==Character.toString('r') //2nd

2nd evaluates to false but it should evaluate to true since i am converting 'r' to a String. Why i am getting false as a result?

By doing this i am able to make the condition true

 //char s=name.charAt(0);
 // s=='r'

;

Answer 1

Try it as: s.equals(Character.toString('r'). For more details What's the difference between ".equals" and "=="?

Answer 2

Instead of comparing Strings with == you should use equals().

String s="rahul".substring(0, 1);
System.out.println(s.equals(Character.toString('r'))); 

Answer 3

Use .equals instead, see code below:

    //current code
    System.out.println(s==Character.toString('r')); 

    //change to be as follows
    s.equals( Character.toString('r'));
    System.out.println(s.equals( Character.toString('r')));
