JAVA中如何取得一个变量的类型

class Test 
{
public static void main(String[] args) 
{
int i=1;
System.out.println(getType(i));
}
public static String getType(Object o){
return o.getClass().toString();
}
}

public class Test15 {
public static void main(String[] args) 
{
int i=1;
Integer i1 = 2;
double d = 1.8;
long l = 76;
boolean b = false;

System.out.println(getType(i));
System.out.println(getType(i1));
System.out.println(getType(d));
System.out.println(getType(l));
System.out.println(getType(b));
}
public static String getType(Object o){
return o.getClass().toString();
}
public static String getType(int o){
return "int";
}
public static String getType(byte o){
return "byte";
}
public static String getType(char o){
return "char";
}
public static String getType(double o){
return "double";
}
public static String getType(float o){
return "float";
}
public static String getType(long o){
return "long";
}
public static String getType(boolean o){
return "boolean";
}
public static String getType(short o){
return "short";
}
}

obj.getClass().getName()   ===〉    java.lang.Integer
obj.getClass().toString()  ===〉    class java.lang.Integer

public static void getType(Object object) {
int length = object.getClass().getName().lastIndexOf(".");
String type = object.getClass().getName().substring(length + 1);
System.out.println(type);
}
基本类型不能得到
