separated by spaces, with no extra space after the last element. Extend your program from Question 1 to use this method to print the array after reading
编写一个Java程序,实现对一个整数数组进行排序,并输出排序后的结果。 ```java import java.util.Arrays; public class ArraySorter { public static void main(String[] args) { int[] numbers = {5, 3, 8, 1, 6}; Arrays.sort(numbers); System.out.println("Sorted numbers: " + Arrays.toString(...
在Java中,`Arrays.sort()`方法对字符串数组进行排序时,根据的是字典顺序(按字符的Unicode值比较)。原数组内容为`{ "size", "abs", "length", "class" }`:1. 比较各字符串首字母: - `"abs"`(a开头)字典序最小; - 接下来是`"class"`(c开头); - 然后是`"length"`(l开头); - 最后是`"size"...

String[] aRr = new String[10];这样只是声明了aRr这个数组变量，没有对数组内容进行初始化，而你的数组类型是String，String的默认值是null，所以你的每一个aRr[i]都为null，自然就抛出NullPointerException了。这样初始化一下就行了：for(int i=0;i<aRr.length;i++){ aRr[i] = "";} 呵呵...
