Question

用eclipse运行java：用键盘输入数据后排序

用字符串输入流编写程序，运行都没问题，就是运行后在控制台输入数据后，无法进行排序啊

Answer 1

冒个泡就好了for(int i=0;i <=集合大小-1; i++){for(int j=0; j<集合大小-i-1; j++){int temp = arr[j];if(arr[j]>arr[j+1]){arr[j]=arr[j+1];arr[j+1]=temp;}}}

Answer 2

import java.io.BufferedReader;
import java.io.IOException;

public static void main(String[] args) {

String str[] = new String[10];

new InputStreamReader(System.in));
try {

while (stringTokenizer.hasMoreTokens()) {
str[i] = stringTokenizer.nextToken();
i++;
}
for (i = 0; i < 10; i++)
try {
