all of type output in java code example

Example: java print type of object

//Example:
Integer number = 15;
System.out.println(number.getClass().getName());

//This print to console the fully qualified name of the class, which for the example is:
java.lang.Integer

//If you want a more concise output, you can use instead:
System.out.println(number.getClass().getSimpleName());

//getSimpleName() give you only the name of the class:
Integer

//Printing the type of primitive variables is a bit more complex: see this
