求大神解答8-1

错的：

public class HelloWorld {

public static void main(String[] args) {

int[] scores=new int[]{89,-23,64,91,119,52,73};

HelloWorld hello=new HelloWorld();

hello.rank(scores);}

public void rank(int[] arrays){

int[] score=new int[7];

for(int i=arrays.length-1;i>=0;i--){

if(arrays[i]<0&&arrays[i]>100){continue;}

else

score[i]=arrays[i];}

Arrays.sort(score);

System.out.println(score[6]+"\n"+score[5]+"\n"+score[4]);}}

对的：

import java.util.Arrays;

public class HelloWorld {

public static void main(String[] args) {

int[] scores=new int[]{89,-23,64,91,119,52,73};

HelloWorld hello=new HelloWorld();

hello.rank(scores);}

public void rank(int[] arrays){

int[] score=new int[7];

for(int i=arrays.length-1;i>=0;i--){

if(arrays[i]>=0&&arrays[i]<=100){ score[i]=arrays[i];}

else continue;}

Arrays.sort(score);

System.out.println(score[6]+"\n"+score[5]+"\n"+score[4]);}}
