Question

I came across this question in a Java exercise and I keep getting a memory address printed.

Write code for the following class;

public class MyClass 
{ 

} 

such that the printed result of:

MyClass cls = new MyClass("Test Class"); 
System.out.println(cls); 

will be “Test Class”.

(You will need to write the whole class, and use a parameter in the constructor in your answer).

Answer 1

You need to override the toString() method for the above to work, and add a constructor like this:

public class MyClass {
    private String message;
    public MyClass(String message) {
        this.message = message;
    }
    @Override
    public String toString() {
        return message;
    }
}
