```
int A = 300;
int B = 400;
int C = 1000;
int D = 500;
int []abcd = {A,B,C,D};
Arrays.sort(abcd); // the sequence of array elements will be {300, 400, 500,1000}
```

I wanted to change the value of the variables A,B,C,D according to their location in the array after sorting.

e.g variable A is located at index 0, so the value of A change to 1 instead of 300,

variable B is located at index 1, so the value of B change to 2 instead of 400,

variable D is located at index 2, so the value of D change to 3 instead of 500,

variable C is located at index 3, so the value of C change to 4 instead of 1000,

The final value of the variable will be:

A = 1;

B = 2;

C = 4;

D = 3;

## Best Solution

A naive way to do it would be to go through each element of the array, checking the values as you go:

If going down this approach, of course, turn it into a function that accepts the array, the value to search for, and returns its index within the array.
