replaceChar() -- You are given a String and a character, and want to replace each occurrence of the character in the String with '*'. Your method should return that modified String.


replaceChar("foo", "o") → "f**"
replaceChar("yellow balloon", "o") → "yell*w ball**n"
replaceChar("capital", "a") → "c*pit*l"

...Save, Compile, Run (ctrl-enter)

public String replaceChar(String str, char ch) { }
