String replace() in java

We have a 

String s="my name is bob";
System.out.print(s.replace("a","p"));   // so here a replace to p

but I want a variable in the place of a

example 

char o='a';
system.out.print(s.replace(o,"p"));

But here it is giving an error so how can be put a variable inside a replace method is there any way to do it?

The two variables you give to String.replace have to be the same value (""). This means what's in is a string so you have to change "p" to 'p' or change char o = 'a' to String o = "a".

There is no suitable method found for replace(char,String)

Try this:

String s="my name is bob";

String o="a";
System.out.print(s.replace(o,"p"));

Change char o to String o

Replace is expecting string parameters Also try using replaceAll() if you what to replace all these characters, not just the first one.

String replace takes two chars as its input and replaces the old with the new. For your example you'd need to make the p a char.

String s="my name is bob";
System.out.print(s.replace('a','p'));
//Result - my npme is bob
