Java program compiles but does not executes

[ISAIAH]

Hello,
I knew working netbean side but unfortunately the program that compiles but does not executes. Please help it is making me crazy.

import java.util .*;

Public class classeleve {
String name;

int nbnt;
int[] nt;
Public void Pupils(String name,int nbnt)
{

this.name= name;

this.nbnt= nbnt;

}
Public int GetNote(int num)
{
return nt[num];
}
Public void SetNote(int num,int nt)
{
this.nt[num]= nt;
}
Public void setNotes( int [ ] has )
{
}
Public void SaisirNote()
{
Scanner inp =new Scanner(System.in);
System.out.System.out.println("enter the grade of the student"+ Name +")");
for(int i =0; i <nbnt; i + +)
{
System.out.System.out.println("enter the nt num ("I + +")");
nt[i]= inp.nextInt();/ / This is where it stops running
}

}
Public double Average( )
{
int i =0, sum =0, Mean =0;
while(i <nbnt)
{
sum + = grade[i];
i + +;
}
mean = sum / i;
return sum;
}
Public int Notemaximale( )
{
int i =0, max = grade[0];
for(i =1; i <nbnt; i + +)
{
if(max <nt[i])
= max rating[i];
}
return max;
}
Public int Noteminimal( )
{
int i =0, min = grade[0];
while(i <nbnt)
{
if(min> nts[i])
min = grade[i];
}
return min;
}
Public void display()
{
System.out.System.out.println(name);
for(int elements: nt)
System.out.System.out.println(elements);
}
}

Hi,
I think you never initialized the table note [], there must be a moment you declare it as:

nt[]=new int[nbnt]

It is best to do in your after builders instantiated nbnote. Just try this and if you have any more problems then post back.

Hello,
Thanks but even if I initialize the problem and always that's what the compiler writes in performance:

Exception in thread "Hand" java.lang.ArrayIndexOutOfBoundsException: 0
        Has classeleve.SaisirNote(classeleve.java:39)
        Has Hand.hand(Hand.java:25)
Java Result: 1
BUILD SUCCESSFUL (Total time: 11 seconds)

Any help on this.

Hello,
I think you should add this to your code-

Public void Pupils(String name,int nbnt)
{
this.name= name;
this.nbnt= nbnt;
this.nt = new int[nbnt];
}

Otherwise a small remark: you should go see the naming conventions for Java code is easier to read when it follows these conventions.

Hi,
Following the error, you must exit a table here, see below

nt[i]= input.nextInt();

Are you sure that your table is large enough notes for all your charged?
Look to ArrayList or Vector if you do not know in advance cb you will note ( "table" Extensible)

Hello.
I tested your code. It will function properly if you initialize your chart notes. You have the choice between initialize in your class as follows:

int[] nt = new int [MAX];

With a constant MAX.
Or you initialize in the hand when the user inform you of the number of points associated with each pupil, as follows:

Dupont.nt = new int[nbrePtDupont];
Durant.nt = new int[nbPtDurant];

Good luck.
