## 数组的使用(Use of arrays)

``````package array;
import java.util.Arrays;
public class demo04 {
public static void main(String[] args) {
int[] a = {1,2,3,456,74,89,25};
// toString打印或遍历数组元素
System.out.println(Arrays.toString(a));
printarrays(a);
Arrays.sort(a);//Arrays方法对数组进行排序
System.out.println();//换行
System.out.println(Arrays.toString(a));Arrays.fill(a,0)//把数组a全部赋值为0
}
public static void printarrays(int[] a1){
for (int i = 0; i < a1.length; i++) {
if(i==0)
{
System.out.print("[");
}
if(i==a1.length-1)
{
System.out.print(a1[i]+"]");//最后一个数据时输出数据和"]"
}
else
System.out.print(a1[i]+", ");
}
}
}
