Just before relocating on to apply, Let's take a look at an case in point system exactly where we will declare variables and assign values to them: public course HelloWorld community static void main(String[] args) int a; int b = five; String s = “Hi, World!”; a = two; Program.out.println(a); Technique.out.println(a + b); Process.out.println(s); In This system, we to start with declared an int variable named a but didn't promptly assign it a price. Then we declared an int variable named b and "set" the value five in it. Then we declared a string named s and assigned it the worth "Hi there, Earth!"

We currently know how to print to the console, but how do we read from it? For this, we make use of the Scanner course. To use Scanner, we to start with need to have to create an occasion of the class. We can easily do this with the following code: Scanner scanner = new Scanner(Process.in); The moment We now have designed an occasion of Scanner, we could use the following() system to read through enter from the console or nextInt() if we must always browse an integer. The following code reads a amount in the console and prints it into the console:
