Instanceof 測試

如果要用來判斷傳入的是那種型態，參考如下 :

public class InstanceoftTest {


InstanceoftTest(){

String s = "this is String";
Integer i = new Integer(1);
BigDecimal b = new BigDecimal(2.34);
checkWithInstanceof(s);
checkWithInstanceof(i);
checkWithInstanceof(b);
}

public static void checkWithInstanceof(Object o){

if(o instanceof Integer){
System.out.println("Your Class Type is Integer");
}else if(o instanceof BigDecimal){
System.out.println("Your Class Type is BigDecimal");
}else{
System.out.println("Your Class Type will conver String");
}
}



}
