## Java Language Keywords

> Here's a list of Java's keywords. These words are reserved--you cannot use any of these words as names in your Java programs. `true`, `false`, and `null` are not keywords but they are reserved words, so you cannot use them as names in your programs either.

> `abstract` | `double` | `int` | `strictfp` **
> `boolean` | `else` | `interface` | `super`
> `break` | `extends` | `long` | `switch`
> `byte` | `final` | `native` | `synchronized`
> `case` | `finally` | `new` | `this`
> `catch` | `float` | `package` | `throw`
> `char` | `for` | `private` | `throws`
> `class` | `goto` * | `protected` | `transient`
> `const` * | `if` | `public` | `try`
> `continue` | `implements` | `return` | `void`
> `default` | `import` | `short` | `volatile`
> `do` | `instanceof` | `static` | `while`

> * indicates a keyword that is not currently used
> ** indicates a keyword that was added for Java 2
