public class Sort_Bubble {

	public static void main(String[] args) {
		int[] arr = {23,12,3,45,25,46,75,15,12,52};
		
		for(int i=arr.length-1;i>=0;i--){
			for(int j=0;j<i;j++){
				if(arr[j]>arr[j+1]){
					int temp = arr[j];
					arr[j] = arr[j+1];
					arr[j+1] = temp;
				}
			}
		}
//查看結果~~
		for(int i=0;i<arr.length;i++){
			System.out.print(arr[i]+" ");
