Java Operators

As in JavaScript, operators are an important part of programming in Java. Here's an example adding two values using the Java + operator:

public class app
{
    public static void main(String[] args)
    {
        int int1 = 130, int2 = 250, sum;

        sum = int1 + int2;

        System.out.println(int1 + " + " + int2 +
            " = " + sum);
    }
}

Here are the results of this code:

%java app
130 + 250 = 380

So what operators are available in Java? Table 10.1 contains all of them—note that JavaScript shares nearly all of them as well.
