Question

I am to modify a question to that it drops the lowest score when determining the test scoer average and letter grade. I have my program running however it does not drop the lowest score and the grade is messes up.

my program

public class MyClass {
private String[] names; // names of the studi (sorry a fall back on a former life)
private char[] grades; // self explanatory
private int[][] scores; // one for the gipper

// To my class and to initialize the new vaiables
public MyClass() {
names = new String[5];
grades = new char[5];
scores = new int[5][4];
}

// to return names
public String[] getNames() {
return names;
}

// to return the grade... but not stats
public char[] getGrades() {
return grades;
}

// to return the scores
public int[][] getScores() {
return scores;
}

// To display details of 5 students
public void displayDetails() {
int avg, sum;
System.out.println(" ************ Details Entered Are ************");
for (int i = 0; i < 5; i++) {
avg = 0;
sum = 0;
for (int j = 0; j < 4; j++) {
sum += scores[i][j];
}
// sum contains total of 4 scores
// Calculating average using sum
avg = sum / 4;
System.out.println("Student Name:" + names[i] + " Average Score:"
+ avg + " Grade Scored:" + grades[i]);
}
}

public String getStudentByName(String name) {
// As specified,a method to return details of a given Student
for (int i = 0; i < names.length; i++) {
if (names[i].equalsIgnoreCase(name)) {
// If the Student name matches in the stored names
float avg = 0.0f;
for (int j = 0; j < 4; j++) {
avg += scores[i][j];
}
avg = avg / 4; // Calculated the average
return "Student Name:" + names[i] + " Average Score:" + avg
+ " Grade:" + grades[i];
// It will return the details as the student was found
}
}
return "Student not available"; // If Student is not found in the Stored
// array } }
}

public void setNames(String names, int i) {
this.names[i] = names;
}

public void setGrades(char grade, int i) {
this.grades[i]= grade;
}

public void setScores(int scores, int i, int j) {
this.scores[i][j] = scores;
}

}
