方法sort(int [] a)在Java中做什么?
java.util.Arrays类的 sort(int[]) 方法将指定的整数值数组按升序排列。
示例
import java.util.Arrays; public class ArrayDemo { public static void main(String[] args) { int iArr[] = {2, 1, 9, 6, 4}; for (int number : iArr) { System.out.println("Number = " + number); } Arrays.sort(iArr); System.out.println("排序的int数组是:"); for (int number : iArr) { System.out.println("Number = " + number); } } }
输出结果
Number = 2 Number = 1 Number = 9 Number = 6 Number = 4 排序的int数组是: Number = 1 Number = 2 Number = 4 Number = 6 Number = 9
