Using Braces Effectively in Java

Using Braces Effectively in Java

Although using braces is a a common practice, it is sometimes very misleading and it can take hours to figure out what is wrong.

A simple way to avoid such problems is to use the curly braces ({}) as needed to avoid ambiguity.

Below is a simple code sample that does not have braces, and hence, there are problems during compilation.

class UsingBraces{   public static void main(String args[])   {      UsingBraces usingBraces = new UsingBraces();      usingBraces.proceed();         }      private void proceed()   {      for (int i=0;i           System.out.println("i: " + i); System.out.println("i: " + 5);      //In the above line, the statement System.out.println("i: " + 5); is not part of the loop.       //If you try replacing the value 5 as i, the compiler itself throws an error indicating that the variable i cannot be identified.   }}/*

Expected output:

[root@mypc]# java UsingBracesi: 0i: 1i: 5*/
