Print Object of a Class in Java

class TestClass {
}
public class Main {
    public static void main(String[] args) {

        // create an object of the Testclass
        TestClass obj = new TestClass();

        // print the object
        System.out.println(obj);
    }
}

• This program will help in understanding the method of printing the value of a class object.
• In the following example we have created a TestClass, which does not contain any method initially.
•  In the Main method, we instantiate an object of TestClass.
• But when we try to print this object, although no error occurs, the type of the value turns out to be in hash-code form.
• As the default format employed by toString() method is in hash-code.
• Therefore, we require overriding technique to convert the return type into string format.
• This time we create our own toString() method in TestClass and override it using @Override key word.
• The return value will be object- a string, now.
