Ans: program will compile but not run i.e. runtime error.
Program:
// define a class one in which no main method will define.
class One
{
// define toString method.
public String toString()
{
return "hello toString method";
}
// define display method
void Display()
{
// define print function
System.out.println("hi display");
}
}
//define another class B that extends the class One
class B extends One
{
//define main method in class B
public static void main(String args[])
{
//create a constructor of class one
One a=new One();
// call print function
System.out.println(a);
}
}
