Question

java面试题：将含有20个数的数组按从小到大的顺序输出结果.

Answer 1

import java.util.Arrays;
import java.util.Scanner;

public class test {

public static void main(String[] args) {
// TODO Auto-generated method stub
Object[] obj=null;
int[] l=null;
int m=0;
for(int i=0;i<10;i++){
People people = new People();
people.setHeight(i);
obj[i]=people;
}
for(Object k:obj){

l[m] =(People)k.getHeight;
m++;
}
Arrays.sort(l);

}

}

追问

不好意思，请问程序里面的people对象或者类是什么？？？不懂

追答

People 是个类，哎呀自己上网搜搜，多的是，我也不知道你是要数组还是线性表排序..冒泡排序两个数组搞得定了

public class SortTest {
public void sort(int[] args){

for(int m : args){
System.out.print("排序前 "+args[m]+" ");
}

int time1 = 0,time2 = 0;
for(int i = 0 ; i args[j]){
temp = args[j];
args[j] = args[i];
args[i] = temp;
}
}
}
System.out.println();
System.out.println("外循环次数："+time1+"内循环次数："+time2);
for(int n : args){
System.out.print("排序后 "+n+" ");
}
}
public static void main(String[] args) {
int[] arg = new int[]{2,1,4,5,8,7,6,3,9,0};
new SortTest().sort(arg);
}
}
