数组反射机制的应用小例------getComponentType - JAVA

[java]
package Ref;

import java.awt.Button;

public class SampleComponentReflection {

public static void main(String[] args) {
int[] ints = new int[2];
Button[] buttons = new Button[6];
String[][] twoDim = new String[4][5];
String[] two = new String[4];

printComponentType(ints);
printComponentType(buttons);
printComponentType(twoDim);
printComponentType(two);
}

static void printComponentType(Object array) {
Class arrayClass = array.getClass();
String arrayName = arrayClass.getName();
Class componentClass = arrayClass.getComponentType();
String componentName = componentClass.getName();
System.out.println("ArrayClass:" + arrayClass + " ,----ArrayName: "
+ arrayName + ",------- Component: " + componentClass);
}

}
输出结果：
[ html]
ArrayClass:class [I ,----ArrayName: [I,------- Component: int
ArrayClass:class [Ljava.awt.Button; ,----ArrayName: [Ljava.awt.Button;,------- Component: class java.awt.Button
ArrayClass:class [[Ljava.lang.String; ,----ArrayName: [[Ljava.lang.String;,------- Component: class [Ljava.lang.String;
ArrayClass:class [Ljava.lang.String; ,----ArrayName: [Ljava.lang.String;,------- Component: class java.lang.String
