Question

JAVA中如何用while循环实现一个整数的倒序输出，例如输入12345，输出54321

Answer 1

int i = 12343465;
int m = 0;
while (i != 0) {
m =i%10;
System.out.print(m);
i = i/10;
}

Answer 2

String str = "123456";
int index = str.length();
while (index != 0) {
System.out.print(str.substring(index - 1, index));
index--;
}

Answer 3

public static void reverseString (String str){
StringBuffer stringBuffer = new StringBuffer (str);
System.out.print(stringBuffer.reverse());
}

把你的整形变为字符串，通过reverse方法倒序输出提交回答
