Method:

public String toString()
Returns:

A string representation of this class object. The string representation is the string "class" or "interface", followed by a space, and then by the fully qualified name of the class in the format returned by getName(). If this Class object represents a primitive type, this method returns the name of the primitive type. If this Class object represents void this method returns "void".


Examples


package com.logicbig.example.clazz;

public class ToStringExample {

    public static void main(String... args) {
        String s = String.class.toString();
        System.out.println(s);
    }
}

Output

class java.lang.String




package com.logicbig.example.clazz;

public class ToStringExample2 {

    public static void main(String... args) {
        String s = Runnable.class.toString();
        System.out.println(s);

        s = Deprecated.class.toString();
        System.out.println(s);
    }
}

Output

interface java.lang.Runnable
interface java.lang.Deprecated




package com.logicbig.example.clazz;

public class ToStringExample3 {

    public static void main(String... args) {
        String s = int.class.toString();
        System.out.println(s);

        s = int[].class.toString();
        System.out.println(s);

        s = void.class.toString();
        System.out.println(s);
    }
}

Output
