数组排序java内置函数

在Java中，可以使用Arrays类的sort()方法来对数组进行排序。该方法位于java.util包中，因此在使用之前需要先导入这个包。该方法可以按照升序对数组进行排序，即从小到大。下面是使用Arrays.sort()方法对数组进行排序的示例代码：

import java.util.Arrays;

public class ArraySortExample {
public static void main(String[] args) {
int[] array = {5, 3, 9, 1, 7};
Arrays.sort(array);
System.out.println(Arrays.toString(array));
}
}

运行这段代码，输出结果将为：[1, 3, 5, 7, 9]。这就是通过Java内置的数组排序函数对数组进行排序的方法。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
