How to assign an array position number plus 1 to as value of the array ?

Question

how to set a range
eg I would.like an array of 125 with values of 1-126

Answer 1

Simple loop will accomplish that. Just assign the i+1 value to it as it iterates through the loop.

Answer 2

If I understood your question, maybe this is what you're trying to do?

(I set the array to 5 because it's easier to test that way. You can set it to 126, and that'll generate the result you seek.)

int[] intArray = new int[5];
int counter = 0;

while( counter < intArray.length ) {
intArray[counter] = counter + 1;
System.out.println("Index " + counter + ": " + intArray[counter] );
counter++;
}

Answer 3

@Anges No problem. To the best of my knowledge, I don't think the fill method allows you to specify a range of integers to use for the value. I'll poke around and see what I can track down for you though.

Also, you could always create a class for your own custom functions, and just create a method to accomplish this goal. Then you can use your own custom functions in any of your other code when you need to do something like this.

Answer 4

Yes I think this will work, thank you.
would have been nice if I could make the fill method work
int [] decasc =new int[125];
Arrays.fill(decasc,1-125);
for(int value:decasc){
System.out.println(" the range is "+value);
but cannot find the right syntax.
tried 1..125
1 to 125

Answer 5

@Anges Here you go bro: This will give you the "fill" affect you're looking for, except you control the value range and it'll be sequential.

import java.util.stream.IntStream;

public class Program
{
public static void main(String[] args) {

int[] intArray = IntStream.rangeClosed(1, 126).toArray();

for(int x : intArray)
{
System.out.println(x);
}

}
}

Answer 6

yeay thank you so much, this is perfect

Answer 7

@Anges Okay, excellent! I'm glad it'll be of some use to you. Best of luck with whatever you're working on!

Answer 8

I'm not sure but I think this would do it

#include <iostream>
using namespace std;

int main() {

int x;
int arr[125];

while (x != 125) {
x++;
arr[x] = x;
}

return 0;
}

Answer 9

thank you
I tried the
int [] decasc =new int[126];
Arrays.fill(decasc,+1);
but that didnt work out well
