    Default Comparison int and Integer

    I'm beginner in Java and traying to campare 2 types: int and Integer. There is a code:

    class validateIntAndInteger
    public boolean validateIntAndInteger (int number1, Integer number2) {
    if(number1 == number2) {
    System.out.println("Numbers are equals.");
    } else {
    System.out.println("Numbers are not equals.");
    class Application
    public static void main (String[] args) throws java.lang.Exception
    int number1 = 2;
    Integer number2 = 4;

    validateIntAndInteger personCheck = new validateIntAndInteger();{
    personCheck.validateIntAndInteger( number1, number2 );

    But there is a error: missing return statement, line 9
    I don't know why?
    Anyone can help?
    Thank You

    Default Re: Comparison int and Integer

    missing return statement, line 9
    If a method is defined to return a value, then the method must have return statement(s) that return a value of the type used in the method's definition.
    Add a return statement at line 9.
    Or change the method's definition so it does not return a value.

    Please edit your post and wrap your code with code tags:


    to get highlighting and preserve formatting.
