Sample questions:

Sample-1: Which of the following lines contain a compiler error?

public static void main(String[] args){       // line 1     String greet = “Hi, there. “;         // line 2     int number, double name;      // line 3     System.out.println(greet + “Your number is ” +  number) ;      // line 4 }

A)  line 1

B)  line 1 and line 2

C)  line 3

D)  line 4

Answer: C

Explanation: Java does not allow multiple data types to be declared in the same declaration. In line 3, int and double types are declared in the same line, which is an error. So, option C is the correct answer.

Sample -2: What is the output of the following code?

public class FooBarMama {     public FooBarMama() {     System.out.println(“FooBarMama constructor”);} } public class FooBar extends FooBarMama {        public FooBar() {     System.out.println(“FooBar constructor”);} } public static void main(String[] args) {     FooBar f = new FooBar();     System.out.println( f ); }

A)   FooBarMama constructor                                                        B)  FooBarMama constructor

FooBar constructor

C)   FooBar constructor                                                                 D)  Code has a compiling error

E) Code has a Runtime error

Answer: A

Explanation: When an object is created, one constructor will be called for every class in its inheritance hierarchy. By default, Java  calls the constructor you asked for, and then the no-argument constructor for every superclass (parent class). Here FooBar is a subclass (child class) and FooBarMama is the superclass (parent class).

Sample-3: Given that SC is an scanner object. Which of the following code stores users value into an array?

A)

int[] d = new int[10]; for (int i = 0; i < d.length; i++) {     SC.nextInt(); }

B)

int[] d = new int[10]; d[i] = SC.nextInt();

C)

int[] d = new int[10]; for (int i = 0; i < d.length; i++) {     d[i] = SC.nextInt(); }

D)  None of the above is correct

Answer: C

Explanation: If you want to fill an array with keyboard input values you will need a loop to repeatedly get the input and put the value into the array. Loop continues until it reach to the length of the array.  Then use nextInt() method for assigning  keyboard value.
