Arrays方法

public class arrySort2 {
public static void main(String[]args){
//定义二维数组并随机数填充
int a[] = new int[]{12,6,58,9,35,74};
//复制
int[] b = Arrays.copyOfRange(a,0,3);
for(int each:b){
System.out.println(each);
}
//排序
Arrays.sort(b);
//转换为字符串
System.out.println(Arrays.toString(b));
//搜索，使用binarySearch方法前需排序
System.out.println(Arrays.binarySearch(b,6));
//判斷數組是否相同
System.out.println(Arrays.equals(a,b));
}
