Java 10 - Features and Review

Java 10
-----------
1. Time-based release versioning
= New release every six months
= LTS every 3 years starting JDK 11 (September 2018)
= Every month there will be an update release (10.0.1, 10.0.2,etc)

2. Local Variables Type inference - Scala, Kotlin, Go
= Local Scope
= Global Scope
= Dynamic Type changing
= With Lists

3. Changes to Garbage Collector
= isolation of different garbage collectors source code (it will be easier to add new GCs and easier to exclude a GC from JDK build)
= Parallel Full GC for G1 (from Java 9 G1 is the default GC. G1 is designed to avoid full GC, but when dealing with concurrent collections,it falls back with full GC)
In Java 9, G1 uses only single threaded GC, Java 10 has parallel full GC for G1

4. Heap Allocation for alternative devices

5. Java Based JIT Compiler (Grool)- Experimental
= already added in Java 9, but can be enabled using command line arguments in Java 10

6. Root Certificates for JDK 10

demo.java
---------------
import java.util.List;
class demo{
//var no=10; no type inference allowed in global level
public static void main(String a[]){
var name="Java 10"; //No datatypes mentioned, but the compiler understands the type based on the value assigned
//Type inference can be used only in local variables
System.out.println(name);
//name=1; //dynamic type inference changing is not allowed
var numbers=List.of(1,1.2,"Data");
System.out.println(numbers.get(0)+"::"+numbers.get(1)+"::"+numbers.get(2));
}
}
