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
