I would like to remove a particular number from the array
Integer[] arr = new Integer[7];
for (int i = 0; i < arr.length; i++) {
arr[i] = i;
}
Collections.shuffle(Arrays.asList(arr));
This is creating numbers from 0-7 But I dont need 0,I need value from 1-7
Change your int i = 0
to int i = 1
like this:
Integer[] arr = new Integer[7];
for (int i = 1; i < arr.length; i++) {
arr[i] = i;
}
Collections.shuffle(Arrays.asList(arr));
The first value written into your array is 0 because you initialize i
with 0 in the for loop.
Therefore your loop will only insert the values 0 - 6 .
Change this initialisation to i = 1
.
Integer[] arr = new Integer[7];
for (int i = 1; i < arr.length; i++) {
arr[i] = i;
}
