Print the type of a Java variable

Question

In Java, is it possible to print the type of a variable?

public static void printVariableType(Object theVariable){
    //print the type of the variable that          


        

Answer 1

Based on your example it looks like you want to get type of value held by variable, not declared type of variable. So I am assuming that in case of Animal animal = new Cat("Tom"); you want to get Cat not Animal.

To get only name without package part use

String name = theVariable.getClass().getSimpleName() //to get Cat

otherwise

String name = theVariable.getClass().getName(); //to get your.package.Cat

Answer 2

public static void printVariableType(Object theVariable){
    System.out.println(theVariable.getClass())
}

Answer 3

System.out.println(theVariable.getClass());

Read the javadoc.

Answer 4

variable.getClass().getName();

Object#getClass()

Returns the runtime class of this Object. The returned Class object is the object that is locked by static synchronized methods of the represented class.

Answer 5

You can use the ".getClass()" method.

System.out.println(variable.getClass());

Answer 6

You can read in the class, and then get it's name.

Class objClass = obj.getClass();  
System.out.println("Type: " + objClass.getName());
