We Are Going To Discuss About ArrayIndexOutOfBoundsException: Index 3 out of bounds for length 3. So lets Start this Java Article.
ArrayIndexOutOfBoundsException: Index 3 out of bounds for length 3
- ArrayIndexOutOfBoundsException: Index 3 out of bounds for length 3
Indexes starts from 0. Your length is 3 and your counter variable (
i
) starts from 1.
You can usefor (int i = 0; i < 3; i++)
- ArrayIndexOutOfBoundsException: Index 3 out of bounds for length 3
Indexes starts from 0. Your length is 3 and your counter variable (
i
) starts from 1.
You can usefor (int i = 0; i < 3; i++)
Solution 1
because array index start at 0
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
int n = 3;
int[] numbers = new int[n];
float total = 0;
for (int i = 0; i <= 2; i++) {
int row=i+1;
System.out.println("Please type the number " + row + ":");
numbers[i] = input.nextInt();
total = total + numbers[i];
}
System.out.println("The average of the 3 number is: " + total / n);
}

Solution 3
Try this, insert this inside your main method
Scanner input = new Scanner(System.in);
int n = 3;
int[] numbers = new int[n];
float total = 0;
for (int i = 0; i < 3; i++) {
System.out.println("Please type the number " + (i + 1) + ":");
numbers[i] = input.nextInt();
total = total + numbers[i];
}
System.out.println("The average of the 3 number is: " + total / n);

If you’re facing error listed below
Exception in thread “main” java.lang.ArrayIndexOutOfBoundsException: Index 3 out of bounds for length 3
var arr = arrayOf("One","Two","Three")
println(arr[3])
In this Array we just defined three values and index start from 0, So Index 3 doesn’t exist in array that’s why it’s giving this Exception
Try to print index value which includes in Array Such As
println(arr[1])
