How to replace a whole string with another in an array in Java

Question

I want to replace, say String oldString with String newString in an Array along the lines of:

f         


        

Answer 1

You don't need to use replace() in this case, since you are already checking that text[i] is equal to oldString, which means you are replacing the entire String, which means assignment is sufficient:

for (int i = 0; i < text.length; i++) {
   if (text[i].equals(oldString)) {
      text[i] = newString;
   }
}

If, on the other hand, you wanted to replace a sub-string of text[i] which is equal to oldString to newString, you could write:

for (int i = 0; i < text.length; i++) {
    text[i] = text[i].replace(oldString,newString);
}
