Understanding the Long Data Type in Java

Java long behaves differently when used with the letter L and without it.

Code snippet

public class JavaLong
{
   public static void main(String args[])
   {
      JavaLong javaLong = new JavaLong();
      javaLong.proceed();
   }

   private void proceed()
   {
      long longWithL = 1000*60*60*24*365L;
      long longWithoutL = 1000*60*60*24*365;
      System.out.println("With L: " + longWithL);
      System.out.println("Without L: " + longWithoutL);
   }
}

/*

Expected output:

[root@mypc]# java JavaLong
With L: 31536000000
Without L: 1471228928
