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?

import java.io.*; class Master { String doFileWork() throws FileNotFoundException { return "a"; } } class Slave extends Master { public static void main(String[] args) { String s = null; try { s = new Slave().doFileStuff(); } catch ( Exception x) { s = "b"; } System.out.println(s); } //insert a codeline } Choose the correct answers :

class Demo { public static void main(String[] args) { String s = "- " ; try { doMath(args[0]); s += "t "; // line 6 } finally { System.out.println(s += "f "); } } public static void doMath(String a) { int y = 7 / Integer.parseInt(a); } } At commandline if the input is java Demo What will be output?

class Demo { public static void main(String [] args) { int x = 0; // insert code here do { } while (x++ < y); System.out.println(x); } } Which, inserted at line 4, produces the output 12?

class Demo { static String s = "-"; public static void main(String[] args) { new Demo().method1() ; System.out.println(s); } void method1() { try { method2();} catch (Exception e) { s += "c"; } } void method2() throws Exception { method3(); s += "2"; method3(); s += "2b"; } void method3() throws Exception { throw new Exception(); } } What is the result?

class Ping extends Utils { public static void main(String [] args) { Utils u = new Ping(); System.out.print(u.getInt(args[0])); } int getInt(String arg) { return Integer.parseInt(arg); } } class Utils { int getInt(String x) throws Exception { return 7; } } And the following three possible changes: L1. Declare that main() throws an Exception. L2. Declare that Ping.getInt() throws an Exception. L3. Wrap the invocation of getInt() in a try / catch block. Which change(s) allow the code to compile? (Choose all that apply.)

class Demo { public static void main(String[] args) { String s = "-"; switch(TimeZone.CST) { case EST: s += "e"; case CST: s += "c"; case MST: s += "m"; default: s += "X"; case PST: s += "p"; } System.out.println(s); } } enum TimeZone {EST, CST, MST, PST } What is the result?

public class Demo { public static void main(String[] args) { int i=0; i++=i++;//1 ++i=++i;//2 System.out.println("i ="+i); } }

class Demo { public static void main(String[] args) { int[] x = {7,6,5,4,3,2,1}; // insert code here System.out.print(y + " "); } } } Which, inserted independently at line 4, compiles? (Choose all that apply.)
