Java Updates.md

LVTI - (Local Variable Type Inference)

It is an new Update that came in java 8 and got even new Update in java 10.

Public static void main
{
	ArrayList<Integer> obj = new ArrayList<>();
	// instead we can use this
	var obj = new ArrayList<>();
}

It's very new Only updated release in JDK 21. it called Unnamed class and instance main Method.

void main()  
{  
    System.out.println("Hello World!!!");  
}

if We want to Execute single java file in the Terminal . we have compile it then Execute it, but now we don't have to.

public class Threads.Main  
{  
    public static void main(String[] args) {  
        System.out.println("Hello World !!!");  
    }  
}

	public static void main(String[] args)
	{
		String name="Dharunpandi";
		int age=21;
		
		System.out.println(STR."Hi, my name is \{name} and i am \{age} years Old.");
	}
}
