Thread: Java help

Hey,

This is assessed work, so please don't provide any answers. Just some guidance towards where i'm going wrong.

The first part of my code is just user input ect which asks the user to input their coursework weight, module grade and exam grade.

[B]public String[] computeMarks(int[] marks) {   final int[] WEIGHTING = { 60, 40, 50, 40,30, 20 }; String[] results = new String[WEIGHTING.length]; for (int i = 0; i < marks.length / 2; i++) {   int exam = marks[i+6]; int cw = marks[i+6]; int weight = WEIGHTING[i]; int formula = ((cw + weight) + (exam * (100 - weight)) / 100);   if (formula >= 40){	results[i]="PASS"; } else if ((formula < 39) && (formula > 35)){	results[i]="COMPENSATION PASS"; }else{	results[i]="FAIL";   }   }   } }   [/B]

At the top of all this way above i also have

static int[] marks = new int[12];


The program runs and asks the student for their grades and weighting. However once the user inputs all then the program terminates. I don't know why it doesn't state whether they've passed, failed or passed with computation.

anyone...

Try adding a test print to find out what the value of formula is before the series of if statements. Then, if you can't figure out why the value of formula is not what you expect, come back with the details and we'll work that.

Sorry, I don't really understand you. The formula outcome will purely depend on 'x' numbers, so how am i supposed to work out a specific value ? I've got no set numbers, the program is supposed to run using all numbers 1%-100%. My bad if i'm chatting completely off topic from what you meant to say

copeg explained my point just fine, but here's more detail:

public String[] computeMarks(int[] marks) { final int[] WEIGHTING = { 60, 40, 50, 40,30, 20 }; String[] results = new String[WEIGHTING.length]; for (int i = 0; i < marks.length / 2; i++) {   int exam = marks[i+6]; int cw = marks[i+6]; int weight = WEIGHTING[i]; int formula = ((cw + weight) + (exam * (100 - weight)) / 100);   // GB: my suggestion is to add a print statement here to see what // 'formua' is before the if statements: System.out.println( "formula = " + formula );   // GB: I believe your original question is "why don't these // if statements provide results? knowing what 'formula' is // with the preceding print statement should give you some // insight if (formula >= 40) { results[i]="PASS"; } else if ((formula < 39) && (formula > 35)){ results[i]="COMPENSATION PASS"; }else{ results[i]="FAIL";   }   }   }
