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.
