Java array face Test (iv) __java

1 Delete a repeating element in an array
Ideas:
Most of the array problems can be solved by pointers and temporary variables.
Build a temp variable first
and build a temporary pointer n to the first element of the array
Assigns the first value of an array to the TEMP
See if the second value of the array is equal to Temp
If the equality continues
If you don't wait
Array pointer n++
arr[n]= This value
At the same time temp= this value

Public int[] Delete (int arr[]) {
    int len = arr.length-1;
    int n = 0;
    int temp = 0;
    for (int i = 1; i < Len; i++) {
        temp = arr[i];
        if (arr[i + 1] = = temp) {
            continue
        } else {
            n++;

            Arr[n] = arr[i + 1];
            temp = arr[i + 1];
        }}
    return arr;
}
