1. Determine the output when the value of x is zero: if(x >= 0) if(x > 0) System.out.println("x is positive"); else System.out.println("x is negative");   "x is positive"   None of these   "x is positive" and "x is negative"   "x is negative"   Hint Half-n-half Clue   2. The control expression in an "if" statement must be:   an expression with type boolean   an expression with type integer   an expression with either the type boolean or integer   an expression with either the type boolean or integer with value 0 or 1   Half-n-half Clue   3. Consider the following code: class NewString extends java.lang.String   Results in error because java.lang.String isfinal   Compiles successfully   Results in error because class body is not defined   Results in error because the class is not declaredpublic   Results in error because String isabstract   Half-n-half Clue   4. Consider the following code: int i = 1; switch(c)   code is illegal and therefore will not compile   output will be One followed by Two   output will be One   output will be One, followed by Two, and then followed by Three   Half-n-half Clue   5. What will be the output of the following program? class Main2   XXX followed by YYY   Error. Won't compile   YYY   XXX   Half-n-half Clue   6. To print the value of a variable "x" of type int, which of the following expressions can be used: (A) System.out.println("x = " + x); (B) System.out.println("x = " + String.valueOf(x)); (C) System.out.println("x = " + Integer.toString(x)); (D) System.out.println("x = " + (new Integer(x)).toString());   (A), (B), (C) and (D)   (C) and (D)   (B), (C) and (D)   (B) and (D)   Half-n-half Clue   7. What will be the output of the following program? class Main1   YYY   XXX followed by YYY   Error. Won't compile   XXX   Half-n-half Clue
