Automatic conversion between the primitives and the object wrapper class is called

consider the following classes. Class A, Class B extends A, Class C extends B. if we instantiate an object, which order the constructor of the above classes get executed?

What results from attempting to compile and run the following code? public class Ternary{ public static void main(String args[]){ int a = 5; System.out.println("Value is - " + ((a < 5) ? 9.9 : 9)); } }

What will be the result of executing the following code? 1. boolean a = true; 2. boolean b = false; 3. boolean c = true; 4. if (a == true) 5. if (b == true) 6. if (c == true) System.out.println("Some things are true in this world"); 7. else System.out.println("Nothing is true in this world!"); 8. else if (a && (b = c)) System.out.println("It's too confusing to tell"); 9. else System.out.println("Hey this won't compile");

The class AssertionError has "is - a" relationship with which of these classes:

Which of the following uses the same number of bits as the double primitive variable?

If you add int wit a byte , what will be the result?

float fl = 1.2;

A program written in the Java programming language can run on any platform because...
