Java – why consider numeric values using the int parameter method?

class Test {

class Test {
  void m1(byte b) {
    System.out.print("byte");
  }

  void m1(short s) {
     System.out.print("short");
  }

  void m1(int i) {
     System.out.print("int");
  }

  void m1(long l) {
     System.out.print("long");
  }

  public static void main(String [] args) {
    Test test = new test();
    test.m1(2);
  }
}

The output is: int. why does the JVM consider using the method of int parameter?

Solution

Because integer literals are of type int in Java If you want to call someone else, you need a clear cast (if you want to call the long version, add the L suffix.)
