replace String with another in java

Question

What function can replace a string with another string?

Example #1: What will replace \"HelloBrother\" with \"Brother\"?

Example #2

Answer 1

Another suggestion, Let's say you have two same words in the String

String s1 = "who is my brother, who is your brother"; // I don't mind the meaning of the sentence.

replace function will change every string is given in the first parameter to the second parameter

System.out.println(s1.replace("brother", "sister")); // who is my sister, who is your sister

and you can use also replaceAll method for the same result

System.out.println(s1.replace("brother", "sister")); // who is my sister, who is your sister

if you want to change just the first string which is positioned earlier,

System.out.println(s1.replaceFirst("brother", "sister")); // whos is my sister, who is your brother.
