Java is reliable, popular, and easy to use. It runs on any device and has great compatibility. All this makes Java one of the most attractive programming languages for students. Unfortunately, many of them can’t do their homework and order it from java homework help like Getcodinghelp. Let’s figure out how to avoid this and do it yourself in one day.
Dealing with homework on Java
You must organize your process of learning this programming language. It is necessary to study every day for at least 1 – 2 hours.
Training requires concentration. That’s why you have to ask your roommate or family not to disturb you. Turn off notifications on the phone, or better yet, leave it in another room.
So, you have barricaded yourself in the room, cleaning your desk, and you are finally ready to deal with your homework on Java.
But in order to learn, you need to know what to learn. Otherwise, training will turn into chaotic and ineffective stumbling around on the spot. You should make a plan. It gives you an understanding of two things: what you already know and what you still need to learn. When there are gaps in your knowledge, you need to understand your weaknesses and know where to look for information to study. The secret to successful day-to-day Java homework is to study regularly. If you have gaps in your knowledge and feel like missing out, you should consider either attending additional classes, hiring a tutor, or asking a senior student to assist you.
Usually, procrastination is the main enemy which stops students from coping with their Java homework on the same day. Let’s figure out how to deal with it.
Three exercises to overcome the habit of putting things off
Eat that frog
This method works even with experienced procrastinators who have reached this kingdom of unbelievable mastery. The professional lecturer and millennial Brian Tracey offer a way to fight procrastination with the help of frogs.
A frog is the greatest and most important task you will drag out if you don’t change anything about yourself.
The first rule of eating toads: “If you want to eat two toads, eat the first one. In other words, if you have two important tasks in front of you, it is better to start with the bigger, more difficult, more important one.
Train yourself to start doing your Java assignment right away, finish the work and only then move on to the next task. Don’t be tempted to start with an easy task.
Another rule of eating frogs: “If you still have to eat a living frog, then sitting and watching it won’t help.
Perform five simple steps in the Pomodoro technique, and you will not feel the urge to postpone the task any longer.
- Clearly define the task you will perform.
- Set the timer for 25 minutes.
- Work without worrying about anything, and do not look at the time.
- After 25 minutes of work, you have a short break of 5 minutes. Listen to music, drink tea, pet your dog, or watch a short video.
- If your big task is divided into parts, take a longer break after every fourth timer — from 15 to 30 minutes.
You will be pleasantly surprised at how productive you can be, and you will be able to complete the Java task on the same day.
A mouse and the Swiss cheese
You have to imagine a big block of Swiss cheese and yourself as a mouse who wants to enjoy it very much. This cheese is your homework in Java.
But the mouse can not swallow the whole piece at once. That’s why it chooses another strategy — to chew through small holes from different sides of the block until it eats all of it.
You will deal with your task regardless of which side of the block you will decide to take the first bite. Do not think too long about which side you should start biting — just take that first little bite. After a few of these holes, you will better understand the essence of the task and plan the sequence of actions for its implementation.
Seven useful tips for Java students
Avoid creating unnecessary objects and always give preference to “linear” implementation.
As you know, the creation of objects in Java is an expensive operation in terms of productivity and memory usage. Thus, you should create or initialize objects only when you need them.
Return empty collections instead of null
If the function returns a collection with no values, make sure that it is the empty collection returned, not null. This will save you from additional checks for null.
Always use isEmpty() instead of equals() to check the empty row
There are several different ways to check if a row is empty or not, and one of them is abc.equals(“”). Never do it this way. The best way to check whether a row is empty is using the isEmpty() method. It simply compares the length of the row with 0, using method length(). Therefore, this operation is less costly.
Use the rows carefully
If two rows are combined by “+” in the “for” loop, a new String object is created every time. This causes loss of memory and increases the execution time. Also, it is unique to use the constructor when creating a row.
Try to use primitives instead of wrapper classes
Wrapper classes work better than primitives because they store additional information, and primitives are only values. Sometimes the programmer can make a mistake in the code using the wrapper class.
Never drop “java.lang.Exception”
Never drop “java.lang.Exception” at once. This will hinder the use of the indicated exceptions. Drop more specific exceptions or create your own ones if you don’t find them for a specific situation.
NullPointerException is a very common Java exception. This type of exception occurs when we try to access the method or field of the object which is referring to null.
Never handle NullPointerException with try-catch-finally. It is more useful to check the field for null.
