Java 实例 - 输出数组元素

Java 教程 · 2019-02-10 15:14:50

以下实例演示了如何通过重载 MainClass 类的 printArray 方法输出不同类型(整型, 双精度及字符型)的数组:

MainClass.java 文件

public class MainClass { public static void printArray(Integer[] inputArray) { for (Integer element : inputArray){ System.out.printf("%s ", element); System.out.println(); } } public static void printArray(Double[] inputArray) { for (Double element : inputArray){ System.out.printf("%s ", element); System.out.println(); } } public static void printArray(Character[] inputArray) { for (Character element : inputArray){ System.out.printf("%s ", element); System.out.println(); } } public static void main(String args[]) { Integer[] integerArray = { 1, 2, 3, 4, 5, 6 }; Double[] doubleArray = { 1.1, 2.2, 3.3, 4.4, 5.5, 6.6, 7.7 }; Character[] characterArray = { 'H', 'E', 'L', 'L', 'O' }; System.out.println("输出整型数组:"); printArray(integerArray); System.out.println("\n输出双精度型数组:"); printArray(doubleArray); System.out.println("\n输出字符型数组:"); printArray(characterArray); } }

以上代码运行输出结果为:

输出整型数组:
1 
2 
3 
4 
5 
6 

输出双精度型数组:
1.1 
2.2 
3.3 
4.4 
5.5 
6.6 
7.7 

输出字符型数组:
H 
E 
L 
L 
O
