Predict Java program output

class Output { final static short i = 2; public static int j = 0; public static void main(String [] args) { for (int k = 0; k < 3; k++) { switch (k) { case i : System.out.print(" 1 "); case i - 1 : System.out.print(" 2 "); default : System.out.print(" 0 "); } } } }0 2 0 1 2 0

0 2 0 1 2 0

class Test { protected int x, y; } class Main { public static void main(String args [ ]) { Test t = new Test(); System.out.print("x = " +t.x); } }

0, 0 (Default constructors initialize integral variables as 0 in Java)

// filename: Test.java class Test { int x = 10; public static void main(String[] args) { Test t = new Test(); System.out.println(t.x); } }

GeeksforGeeks

class Test { public static void main(String args [ ]) { for(int = i = 0; true; i++) { System.out.print("Hello"); break; } } }

Hello

class Test1 { Test1(int x) { System.out.println("Constructor called " + x); } } // This class contains an instance of Test1 class Test2 { Test1 t1 = new Test1(10); Test2(int i) { t1 = new Test1(i); } public static void main(String[] args) { Test2 t2 = new Test2(5); } }

The output of the program is Constructor called 10 Constructor called 5.

public class Final { int a = 30; public static void main(String[] args) { final int assign; Final b = new Final(); process(b); System.out.println(b.a); process(b); assign = b.a; System.out.println(assign); } public static void process(Final a) { a.a = a.a + 5; } }
