Replaces each substring of this string that matches the literal target sequence

Question
Replaces each substring of this string that matches the literal target sequence with the specified literal replacement sequence. The replacement proceeds from the beginning of the string to the end, for example, replacing "aa" with "b" in the string "aaa" will result in "ba" rather than "ab".@param in The string to be searched and modified.
@param what The sequence of char values to be replaced
@param with The replacement sequence of char values
@return The resulting string
public class StringReplace
{
public static String replace(String in, String what, String with)
{
****** I need help writing the code here **********
}
public static void main(String[] args) {
System.out.println("replace("I went home.", " ", "-") = "" +replace("I went home.", " ", "-") + """);
System.out.println("replace("I watched the ditch.", "tch", "sh") = "" +replace("I watched the ditch.", "tch", "sh") + """);
System.out.println("replace("Not long enough.", "enough...", ".") = "" +replace("Not long enough.", "enough...", ".") + """);
}
}
When you run, it should print:
replace("I went home.", " ", "-") = I-went-home.
replace("I watched the ditch.", "tch", "sh") = I washed the dish
replace("Not long enough.", "enough...", ".") = Not long enough <-- prints out same.
Please help me out. Thank you so much.
