Question 1

Which correctly creates an array of five empty Strings?
◦ String[] a = new String [5];
◦ String[] a = {"", "", "", "", ""};
◦ String[ ] a = new String [5]; for (int i = 0; i < 5; a[i++] = null);
◦ String[5] a;

Question 2

Identify the problems in the following code.

public class Test {
public static void main(String argv[]) {

System.out.println("argv.length is " + argv.length);

}
}

◦ The program has a compile error because String args[] is wrong and it should be replaced by String args[].
◦ The program has a compile error because String argv[] is wrong and it should be replaced by String[] args.
◦ If you run this program without passing any arguments, the program would display argv.length is 0.
◦ If you run this program without passing any arguments, the program would have a runtime error because argv is null.
