import java.util.Arrays;
public class demo {
public static void main(String[] args) {

char[] ch ={'a','c','u','b','e','p','f','z'};
Arrays.sort(ch);
for(int x=ch.length-1;x>=0;x--){
System.out.print(ch[x]+" ");
}
}
}

这样就行了。

import java.util.Arrays;

public class ArrayOP {

public static void main(String[] args) {

char[] chars = { 'a', 'z', 'k', 'q' };

Arrays.sort(chars);// 排序

System.out.print("\n\n顺序输出:");
for (int index = 0; null != chars && index < chars.length; index++) {
System.out.print(" " + chars[index]);
}

System.out.print("\n\n逆顺序输出:");
for (int index = 0; null != chars && index < chars.length; index++) {
System.out.print(" " + chars[chars.length - index - 1]);
}

}

}
