Six Java Tricks & Tips For Better Programming

Java is one of the versatile and widely used programming languages in today’s world. Tricks are everywhere in the 20th Century era. Like all the other things some tips may enhance the work quality and decrease the time needed for that as well. These two things ultimately result from more productivity. Man Java developer friends of us remember those sleepless nights they used to work for completing the coding of apps.

Java Tricks and Tips

Like me, all my fellow developers entrust in optimizing workflows and always look for the shortcuts to improve and enhance productivity. Here I am going to share some kick ass ideas which will enhance your work time productivity and will pull down the percentage of errors during coding.

Always have the shortcuts ready

This is one of the genuine, easy deals before getting into the tougher part. For my novice friends, this is the starter before the main course. To get the all the shortcut keys ready with you, press CTRL+ SHIFT + L while working on Eclipse framework. All the things are simple there.

Trace the errors easily using shortcut codes

Finding the errors of a coded program is very painful, and even sometimes it becomes very frustrating when you do everything to track down the errors but somehow you can’t. Whenever you encounter with something whose source is not clear, use this code below-

import java.io.*;

Exception e = …;

java.io.StringWriter sw = new java.io.StringWriter();

e.printStackTrace(new java.io.PrintWriter(sw));

String trace = sw.getBuffer().toString();

Always merge the hash tables

If you are looking for merging two hash tables one with another, you should iterate with every value even if the process is drastically inefficient. I am giving one sure shot shortcut which allows you to get merged with almost nil fuss.

import java.util.*;

Map m1 = …;

Map m2 = …;

m2.putAll(m1); // adds all elements of m1 to m2

 

Check the date of the string whether that is valid or not

Whenever you encounter some problem specially when you get a string with a date with it and as a coder you want to convert the whole string into an object. The main question arises here how you will change the whole thing into an object so that the string will remain valid for all dates (or regardless of the date).

Keep the String Size Short

It’s counted one of the best ways to optimize Java performance. Always try to keep the string short and compact. You can get several online guides on how to lower the string size of any program. It tunes the while program and helps to run like butter. It will also push the performances to switch on for all the things that are being installed.

I hope, these Java tricks will help you a lot while programming and assembling codes of your new app. These come for help anywhere, from scratching codes to fixing bugs and errors of a final product.
