What is the output of this program?


public class output 
    {
        public static void main(String args[])
        { 
           String str1 = "Intervzew Manza";
           String str2 = str1.replace('z','i');
           System.out.println(str2);
        }
    }

1. Intervzew
2. Manza
3. Interview Mania
4. IntervzewManza
5. None of these

Correct Option: C

replace() method replaces all occurrences of one character in invoking string with another character. str1.replace(‘z’,’i’) replaces every occurrence of ‘z’ in hello by ‘i’, giving Interview Mania.
