   System.out.println(“a[“ +i+”] = “+ a[i]);

• (20 pts) What does this method do?

public static int foo(String [] a)

    {

    int b = 0;

    for (int i = 0; i<a.length; i++)

       {

               b++;

       }

• (40 pts) You coded the following on line 26 of a program called Test.java:

int a[6] = {2,7,8,9,11,16);  //line 26

When you compile, you get the following messages:

Test.java:26: ‘]’ expected

    int a[6] = {2,7,8,9,11,16}; //line 26

             ^

Test.java:26: illegal start of expression

            Test.java:26: not a statement

                 int a[6] = {2,7,8,9,11,16}; //line 26

                                   ^

            Test.java: 26: “;” expected

                 int a[6] = {2,7,8,9,11,16}; //line 26

                                     ^

            Test.java: 26: class, interface, or enum expected

            }
