public int getArrayIndex(int[] arr,int value) { int k=0; for(int i=0;i<arr.length;i++) { if(arr[i]==value) { k=i; break; } } return k; } //Call this method and pass two parameters that are Array and value int indexNum = getArrayIndex(i,9); //here , u hv to pass these parameters to know the index of "9" in array "i"

it will be 1 less than the actual position bcz the in java we start counting index from 0 so i [0] is 6 i [1] is 5 i [3] is 9 //ie index of 9 is 3 in the above code
