Given an array, find all the subsets

int arr[] = {1,2,3,4,5};
int level= 0;

for (int i = 0; i < arr.length; i++) {
System.out.println(arr[i]);
subset(arr[i]+””,i+1,arr);

}
}

private void subset(String i, int level,int[] arr) {

for (int j = level; j < arr.length; j++) {
System.out.println(i+””+arr[j]);
subset(i+””+arr[j],j+1,arr);

}
