Question

比较任意6个数,按从小到大j的顺序输出java

Answer 1

Integer arryNum[];
int count = 0;/* 统计数字 */
boolean judgeIsNum = true;
StringBuffer stringbuffer = new StringBuffer();
Scanner scanner = new Scanner(System.in);
String character;
int memoryNum;
/**
* 任意输入字符
*
* @return 返回输入的内容
*/
// public String inputNum() {
// return null;
// }

/**
* 判断为数字
*/
public void judgmentFigures() {
while (judgeIsNum) {
System.out.println("请任意输入数字，以空格间隔，以回车结束！");
character = scanner.nextLine();
char[] figures = character.toCharArray();
for (int i = 0; i < figures.length; i++) {
if (!(figures[i] >= '1' && figures[i] <= '9')
&& figures[i] != 32) {
judgeIsNum = true;
break;
}
judgeIsNum = false;
}
if (!judgeIsNum)
stringbuffer.append(character);
}
String inputContent = stringbuffer.toString();
String[] numbers = inputContent.split("\\s+");
arryNum = new Integer[numbers.length];
for (int i = 0; i < numbers.length; i++) {
try {
memoryNum = Integer.parseInt(numbers[i]);
arryNum[count] = new Integer(memoryNum).intValue();
count++;
} catch (Exception e) {
/* 如果不出现异常，则说明肯定是数字 */
}
}
}
