How to Write a Block of Code in Java

Program code in a Java program is contained in a block. A block begins with an open curly brace symbol and ends with a close curly brace symbol. As an example, we might write a block of code that contains a variable definition and some console print statements. To write a block of code, follow these four steps.

1. Open your text editor and create a new file. Type in the following Java statements. Notice the curly braces that delimit the block of code.
   


2. Save your file as WriteBlockOfCode.java.


3. Open a command prompt and navigate to the directory containing your new Java program. Then type in the command to compile your program and hit Enter.
   


4. Now you will run your Java program. Type in the command to run the Java runtime launcher and hit Enter. Notice the output from the block of code you wrote in the Java class.
