A Student class extends Person class:
1        class Person
2        {
3                 int heightcm;
4
5                Person()
6                {        this.heightcm=160;         }
7        
8                int getHeight()
9                {        return heightcm;          }
10
11                String display()
12                {        return "Person height is " + heightcm; }
13        }

14        class Student extends Person
15        {
16                int studhtcm;
17                String className()
18                {        return "Student";        }
19
20                public static void main(String args[])
21                {
22                        Person obj = new Student();
23                        System.out.println(obj.getHeight());
24                        System.out.println(obj.display());
25                        System.out.println(obj.className());
26                }
27        }

What will happen on compiling and running the code?

You have created the following class to print some numbers:

public class PrintNumber {
         int a;
         int b;
        
         public void basefunt() {
            a = 0;
            b = 0;
            int[] c = { 0 };
            modify(b, c);
                System.out.println( '' '' + a  + b + c[0]);
         }
    
         public void modify(int b, int[] c) {
            a = 1;
            b = 1;
            c[0] = 1;
         }

          public static void main(String args[]) {
            PrintNumber  p = new PrintNumber();
            p.basefunt();
         }
       }

What will be the output?

Consider the following class: public class Intro { static int a; int b; public Intro() { int c; c = a; a++; b += c; } public void Intro() { int c; c = a; a++; b += c; } public static void main(String args[]) { new Intro(); } } What will happen on compiling and running this class?

You have defined the following methods in one of the java classes: 1 void setId(int newId) 2 private void manageRecord(int RecordNo) 3 protected void delete(int recordNo) 4 boolean isValidRecord(int recordNo) Which of the following methods is incorrect for a class that extends above class?

What will be the result obtained on compiling and running the viewer on .net command prompt?

Which one is a valid way to name the '.java' file containing the above classes?
