How do you know a variable type in java?

Question

Let\'s say I declare a variable:

String a = \"test\";

And I want to know what type it is, i.e., the output should be java.lang.String

Answer 1

Use operator overloading feature of java

class Test {

    void printType(String x) {
        System.out.print("String");
    }

    void printType(int x) {     
        System.out.print("Int");
    }

    // same goes on with boolean,double,float,object ...

}
