以下是示例代码: public class PrintArrayElements { public static void main(String[] args) { int[] numbers = {1, 2, 3, 4, 5}; // 使用for循环遍历数组 for (int i = 0; i < numbers.length; i++) { // 打印每个元素 System.out.println(numbers[i]); } } } 复制代码 输出结果为: 1...
printArray(int[] array):用于打印基本类型int数组的元素。它将数组的每个元素用空格分隔,并打印在一行上。 以下是使用printArray方法的示例: import java.util.Arrays; public class Main { public static void main(String[] args) { Integer[] numbers = {1, 2, 3, 4, 5}; System.out.print("Numbers: ...

在使用集合类时,我们不仅关心容器是如何保存数组的,而且关心如何取元素。本实例先来使用普通for循环遍历ArrayList,从中取出所有序号为奇数的元素。 实现过程 1) 在类的主方法中创建一个ArrayList集合为其指定泛型为Integer类型,并添加10个元素,然后利用for循环遍历ArrayList集合,输出表中序号为奇数的元素。 代码如下:...
for (int i=3; i>=0; i--) {try {int[] arr = new int[Integer.MAX_VALUE-i];System.out.format("Successfully initialized an array with %,d elements .\n", Integer.MAX_VALUE-i);} catch (Throwable t) {t.printStackTrace();}}JAVA ...
