Java~~Write a java program using Blocks~~


A block as a group of statements that are collected together called a compound statement. It is bound by opening and closing braces { }. A class definition is contained in a block. A block statement can be nested withing another block. In Java source code, block statements are executed first, then constructor statements are executed, and then method statements are executed.

Best Example: 

 public class BlockTest{
 public String info;

 public BlockTest(){
 info = ”Constructor:Executed in 2nd step”;
 System.out.println(info);
 }

 {
 info = ”Block:Executed in 1st step”;
 System.out.println(info);
 }

 public void show(){
 info = ”Method:Executed in 3rd step”;
 System.out.println(info);
 }

 public static void main(String[]args){
 BlockTest bt = new BlockTest();
 bt.show();
  }
 }
