QUESTION 1

1. The following dropStudent method from listing 10.6 contains two errors. What are they?

   01 public void dropStudent(String student) {

   02 int locationToZap = -1;

   03 int currLoc = 0;

   04 for (currLoc = 0; currLoc < numberOfStudents && locationToZap == -1; currLoc++) {

   05 if (students[currLoc] == student) {

   06 locationToZap = currLoc;

   07 }

   08 }

   09 if (locationToZap == -1) return;

   10 for (currLoc = locationToZap; currLoc < numberOfStudents; currLoc++) {

   11 students[currLoc] = students[currLoc + 1];

   12 }

   13 numberOfStudents--;

   14 }

   		line 10 should have numberOfStudents - 1 in the condition
   		line 04 should use numberOfStudents - 1 in the condition
   		line 09 should use != as its conditional relation
   		line 13 should be moved to the first line of the method
   		line 04 should omit the locationToZap == -1 in the condition
   		line 03 should be deleted and line 04 changed to be "for (int currLoc....."
   		line 13 should be deleted
   		line 05 should use .equals to compare string objects
