Java 实例 - 输出数组元素
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

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
