Good job on the MathUtilities and PredicateUtilities.
For the string utilities, a few comment. You don't have to call String.format unless there is a format you want, like padding space. So for these methods, you can return the string and concatenate it without calling format.
public String getHelloWorld() {
return "Hello World";
}
public String concatenation(int firstSegment, String secondSegment){
return firstSegment + secondSegment;
}
For getSuffix, what we're expecting is the last three character, that means return input.substring(input.length() - 3);
Please finish up the homework.
