JAVA之数组练习

1、请将1,9,2,5,4,8,3,6,7,10,8存入数组a，然后输出打印；

public class Demoarr01 {
	public static void main(String[] args) {
		int[] a= {1,9,2,5,4,8,3,6,7,10,8};
		for(int i =0;i
			System.out.print(a[i]+" ");
		}
	}
}

import java.util.Arrays;
public class Demoarr02 {
	public static void main(String[] args) {
		int[] a = {1,9,2,5,4,8,3,6,7,10,8};
		Arrays.sort(a);//集合自带的排序方法，把数组a作为参数，可以得到排序后的数组a
		for(int i =0;i
			System.out.print(a[i]+" ");//1 2 3 4 5 6 7 8 8 9 10 
		}
	}
}
