1. class Demo { 2. final static int x2 = 7; 3. final static Integer x4 = 8; 4. public static void main(String[] args) { 5. Integer x1 = 5; 6. String s = "a"; 7. if(x1 < 9) s += "b"; 8. switch(x1) { 9. case 5: s += "c"; 10. case x2: s += "d"; 11. case x4: s += "e"; 12. } 13. System.out.println(s); 14. } 15. } What is the result?

Given:class Demo { static String s = ""; public static void main(String[] args) { try { throw new Exception(); } catch (Exception e) { try { try { throw new Exception(); } catch (Exception ex) { s += "ic"; } throw new Exception(); } catch (Exception x) { s += "mc"; } finally { s += "mf"; } } finally { s +="of"; } System.out.println(s);} }What is the result?

Given: class Mineral { } class Gem extends Mineral { } class Miner { static int x = 7; static String s = null; public static void getWeight(Mineral m) { int y = 0 / x; System.out.print(s + " "); } public static void main(String[] args) { Mineral[] ma = {new Mineral(), new Gem()}; for(Object o : ma) getWeight((Mineral) o); } } And the command-line invocation: java Miner.java What is the result?

class Super { public static int main(int args[]) { System.out.println("Hi"); return 0; } public static void main(String[] args) { System.out.println("Hello"); int[] a={1,2,3,4}; int b=main(a); } } class main extends Super { public static void main(String[] args) { Super ob=new Super(); String[] b={"a","b","c","d"}; ob.main(b); System.out.println("Hi_Hello"); int[] a={1,2,3,4}; int c=main(a); } } what is the result?

Given the following code: public class Demo { public int method(int x) { int r = 1; r += x; if ((x > 4) && (x < 10)) { r += 2 * x; } else (x <= 4) { r += 3 * x; } else { r += 4 * x; } r += 5 * x; return r; } public static void main(String [] args) { Demo ob = new Demo(); System.out.println("OF(11) is: " + ob.method (11)); } } What is the result?
