Java Bubble Sort Method upgrade version

/*
* Upgraded version of bubble sort, can compare integer array, decimal type array

public static <t extends comparable<t>> void Bubblegeneric (t[] arr) {

T temp;
for (int i = 0; i < arr.length-1; i++) {
for (int j = 0; J < arr.length-1-I; j + +) {

Arr[j + 1] = Arr[j];

System.out.println ("Sorted array is:" + arrays.tostring (arr));

}

Method invocation:

Integer arrint[] = {10, 2, 6, 9, 8}; An array needs to be defined as a reference type, and a generic parameter must pass a reference type.
Double arrddouble[] = {11.0,45.2,23.0,46.0,89.6};

Bubblegeneric (arrddouble);
Bubblegeneric (Arrint);
