Environment

  • Tips

  

  

  • Eclipse will create a project folder containing many supporting files Never include these files in your submission

• You can choose other IDEs or editors

  • Visual Studio Code
    • Tutorial: https://code.visualstudio.com/docs/languages/java
  • IntelliJ IDEA
  • NetBeans

• Java version

  • Later than Java 8
  • OpenJDK or Oracle both fine

Run your code

• Use the run/debug feature in your IDE or editor (software-specific)
• Use command-line (more universal and portable way)
  • java command to run
  • javac command to compile .java file to .class file

Workflows

• You may use multiple approaches for different use cases
• Use an IDE and define project every time
• Use an editor and compile/run from command-line
  • Visual Studio Code
• Use jGrasp
  • Works well with our code example repository
  • Works well when working with many projects all at once
    • requires all files in a single folder for each project
    • requires all classes in the default package (no package statements)
