Java 10 Examples

This project shows some examples on how to use the JEP286, the Local-Variable Type Inference, implemented on Java Version 10.

Basic examples:

It's possible to use on primitive types:

var i = 10; // It's an int

Refer to org.java10.examples.BasicExample class.

It's possible to use on Java API classes:

var hello = "Hello!";

Refer to org.java10.examples.ObjectExample class.

Complex example:

It's possible to build developed objects:

var Product = new Product("Good Laptop", 1000f, 10f);

Refer to org.java10.examples.ComplexObjectExample class.

Adding behaviour

It's possible to add a new method to existing class

var modifiedProduct = new Product("An internet product", 8f, 0.5f) {
    public float applyInternetPrice() {
        return getPrice() - 1f + getTax();
    }
};

Refer to org.java10.examples.ProductExample class.

Mixing interfaces

It's possible to mix interfaces.

var seaplane = (Navigable & Flyer) Vehicle::create;

Refer to org.java10.examples.MixinExample class.
