Creating a Method to Replace Characters in a String

Can someone help me create a method that replaces the Characters of a String? For example, 

String nova = antiga.replace('a','1');

This only replaces a letter.

I wanted to create a method for all other letters of the alphabet that I could use whenever I wanted to replace the characters of a certain String.

  • Are you using data input through the console ? Or have some visual screen ?

  • @Matheus as well as visual screen?

    Knowing if it is a graphical interface or console is irrelevant to doubt, the replaceall mentioned below does exactly what you want.

The method itself replace has this purpose. Note that there is an overload that receives two CharSequence's as a parameter.

I mean, you can do it like this

String nova = antiga.replace("alguma coisa", "outra coisa");

See working on repl.it.
