Java Operators

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

Listing . ch10_06.java
 
public class ch10_06
{
    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 ch10_06 
130 + 250 = 380

So what operators are available in Java? Table 10-1 contains all of them. Note that nearly all of them are shared by JavaScript as well.
