在Java中,如何使用方法重载来打印不同类型的数组?
此示例显示使用重载方法打印数组类型(整数,双精度和字符)的方式。
package com.yiibai;
public class PrintingArray {
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("Array integerArray contains:");
printArray(integerArray);
System.out.println("\nArray doubleArray contains:");
printArray(doubleArray);
System.out.println("\nArray characterArray contains:");
printArray(characterArray);
}
}
执行上面示例代码,得到以下结果 -
Array integerArray contains:
1
2
3
4
5
6
Array doubleArray contains:
1.1
2.2
3.3
4.4
5.5
6.6
7.7
Array characterArray contains:
H
E
L
L
O
