In the MyTestPassByReferenceProject, how do you know what the test method is
supposed to do:
public class TestPassByReference{
public static void main(String[] args) {
System.out.println("main:start");
// Create an array of integers andinitialize
// the array with 10, 11, and 12.
int [] ages = {10, 11, 12};
// Print array values. The arrayshould display
// 10, 11, 12
for (int i=0;i<ages.length; i++ ){
System.out.println(ages[i]);
}
System.out.println("main:before calling the test method");
// Call test and pass references to array.
// Since the array is a reference type, what is
// being passed is a pointer to actual array.
test(ages);
System.out.println("main:after calling the test method");
// Print array values again. It nowshould contain changed values.
// display the changed values.
for (int i=0;i<ages.length; i++ ){
System.out.println(ages[i]);
}
System.out.println("main:end");
}
