Simple two-dimensional array program in java

When we want to store elements for a similar type in Java, we take the name of Array. Array stores elements of similar type viz: integer, string, etc.

Moreover, the dimension of the array also varies in Java according to your requirements. Therefore, whenever you have data in a 2D array, you need to print those elements. There are different types of techniques, those you can choose for printing the elements of a two-dimensional array in java. You can use any of those techniques for printing the elements of a two-dimensional array.

All of the techniques, which I will be showing here, have associated examples of codes. Those will provide you with better insights and practical hands-on. You should see carefully the codes that have inline comments to provide better readability. I have also provided outputs in the form of screenshots at the end of each code.

This code searches for the seat number that has just been entered from the console and sets it to 0;. First of all, I would use 1 or any other value to define if a seat is taken, since int values are by default initialized to 0.

If you insist in using 0 you'll have to initialize your whole two dimentional array to a value different than 0. Also, if your seats are defined by a number from 1 to 35 and you only define if a seat is taken or not, I suggest you use an array not a table of booleans. They take the values true and false and are easier to use in this kind of situations.

And the value will be assigned to the element represented by the index. Then, to consult if a seat is already taken:. To check if a seat is taken, the process is slightly different. In this case primitives It'll check if both values are the same.

Later, when you use objects you'll want to use equals instead. Stack Overflow for Teams — Collaborate and share knowledge with a private group. Create a free Team What is Teams?

A three — dimensional array can be seen as an array of two — dimensional array for easier understanding. Skip to content. Change Language. Related Articles. Basics of Java. Operators in Java.

As you can see in the example given above, firstly, you need to declare the elements that you want to be in the specified array.

Secondly, the location of each element needs to particularized as well, since that is where the elements will be stored respectively. As it is visible, the three elements that have been listed simultaneously are as follows:. Hence, the result is printed as 10 20 30 respectively in single lines, since it is a one-dimensional array. The methods used in this article are as follows: Using Standard Method Using Scanner Using String An array is a collection of elements of one specific type in a horizontal fashion.
