java 8 compiler

A core concept introduced in Java 8 is the functional interface (functional Interfaces).By adding an abstract method to the interface, these methods can be run directly from the interface.If an interface defines a unique abstract method , then this interface becomes a functional interface .At the same time, a new annotation was introduced:@FunctionalInterface.Can put him in front of an interface, indicating

Problem Analysis: the engineering codes in myeclipse and eclipse are UTF-8. the Windows encoding GBK and Linux encoding are UTF-8 by default when no exception occurs, however, after installing some packages related to the system environment, I have some doubts about UTF-8 encoding. the final UTF-8 enc

. /** * Represents an operation, accepts a single input argument and returns no * result. Unlike most other functional interfaces, {@code Consumer} are expected * to operate via side-effects. * * Represents an operation, receives a parameter, and does not return a result, unlike most other functional interfaces, the consumer interface expects to operate with a negative effect. (that is, it might manipulate the incoming parameter data, and here is what it says about the negative effect.) ) * * 　　

definition, the compiler will error.　3. In general, the functional interface only defines an abstract method, but the interface eventually has a deterministic class implementation, and the final parent class of the class is object. Therefore, a functional interface can define the public method in object, and the protected method does not.@FunctionalInterfacepublic interface Objectmethodfunctionalinterface {void count (int i); String toString (); Same

In the blink of an eye application upgrade JDK8 has been a few months, the Lambdas expression and Streams APIs did bring the students to the programming efficiency and code readability of the promotion, the code becomes more concise and direct, more in line with human thinking (it seems that the development of programming language is also the spirit of "people-oriented" thinking). ATA on the two new features of the article has been a lot of, immortal everyone eat almost, often home side dishes,

to uninstall the JDK version and install the latest JDK version, you should tell your system where Java has permissions to execute.The default JDK installation path is/usr/java/jdk1.8.0_25/, which is where Java executes, and we should be running one by one and the following commands.alternatives --install /usr/bin/java
