parallel arrays
could somebody please tell me where im going wrong with my code to put grades beside student name i really need some help many thanks ive stuff commented out
code
public class arrays {
public static void main(String[] args) {
String[] students = new String [8];
int[][] grades = new int[8][2];
String tmpStr;
int tmpInt;
students[0] = "Smith";
students[1] = "Jones";
students[2] = "Thompson";
students[3] = "Paul";
students[4] = "Jodan";
students[5] = "Cole";
students[6] = "Dunn";
students[7] = "Nolan";
grades[0][0] = 88;
grades[1][0] = 78;
grades[2][0] = 81;
grades[3][0] = 65;
grades[4][0] = 92;
grades[5][0] = 87;
grades[6][0] = 80;
grades[7][0] = 84;
grades[0][1] = 88;
grades[1][1] = 78;
grades[2][1] = 81;
grades[3][1] = 65;
grades[4][1] = 92;
grades[5][1] = 87;
grades[6][1] = 80;
grades[7][1] = 84;
grades[0][2] = 88;
grades[1][2] = 78;
grades[2][2] = 81;
grades[3][2] = 65;
grades[4][2] = 92;
grades[5][2] = 87;
grades[6][2] = 80;
grades[7][2] = 84;
// Arrays.sort(students);
// Arrays.sort(grades);
// for(int t=0, t<students.length,-1 t++)
// for(int i=0, i<students.length,-1 i++)
// if(students[i].compareTo(students+1)>0){
// tmpStr = students[i];
// tmpInt = grades[i];
// students[i] = students[i+1];
// grades[i] = grades[i+1];
// students [i+1] = tmpStr;
// grades[i+1] =tmpInt;
// }
//
//// print students
int t;
int i;
for(i=0, i< students.length, i++){
System.out.printf(%s - 15s %s* students[i]);
int intSum = 0;
double avgGrad;
for(t=0, t<grades[i].length,t++){
System.out.print(grades[i][t] + " ");
intSum += grades[i][t];
}
int avgGrade = double / intSum;
grades[i].length;
System.out.println( "%5s %s \n" ",grades[i);
}
// }
}
}

Read my blog on this forum about sorting parallel arrays (using a Heapsort implementation). b.t.w. trying to sort parallel arrays is bad design from the old Fortran world ...

As Jos says, parallel arrays is bad design. You really should create a Student class that contains names and grades, and create just one array of Students.
