java中输出数组内容的函数,并将数组内容作为参数_数组的逆序输出

// 对于int型数组int arrays[] = {1,2,3,4,5,4,3,2,1};
for(int temp : arrays) {
    System.out.println(temp);
}
// 或者
for(int i = 0; i < arrays.length; i++) {
    System.out.println(temp);
}

// 对于int型数组int arrays[] = {
  
  1,2,3,4,5,4,3,2,1};
System.out.println(Arrays.toString(arrays));

/*
List<Integer> list = new ArrayList<Integer>();
list.add(2);
list.add(4);
list.add(5);
list.add(3);
*/
Iterator iter = list.iterator();
while(iter.hasNext()) {
    System.out.println((Integer)iter.next());
}

for(Iterator it = list.iterator(); it.hasNext();) {
    System.out.println((Integer)it.next());
}
