Ahead of going on to observe, Let's take a look at an example software where we will declare variables and assign values to them: community course HelloWorld public static void primary(String[] args) int a; int b = five; String s = “Hi, Planet!”; a = two; Program.out.println(a); Program.out.println(a + b); Procedure.out.println(s); In This system, we initially declared an int variable named a but didn't right away assign it a worth. Then we declared an int variable named b and "set" the value 5 in it. Then we declared a string named s and assigned it the value "Good day, Planet!" After that, we assigned the worth two on the variable a that we declared previously, and afterwards we printed the variable a, the sum in the variables a and b, and the variable s to the monitor This plan will Screen the next: 2 7 Good day, Planet! We already learn how to print to your console, but how can we go through from it? For this, we make use of the Scanner course. To use Scanner, we first require to make an occasion of the class. We can try this with the next code: Scanner scanner = new Scanner(Technique.in); After We now have established an instance of Scanner, we are able to use the next() method to browse input within the console or nextInt() if we should always examine an integer. The next code reads a quantity from the console and prints it to your console:
