To import classes from another project in Java, you will need to add the other project as a dependency in your project. There are a few different ways to do this depending on how the other project is set up and how you want to include it in your project. Here are a few options:
build.gradle file:dependencies {
compile project(':path/to/other/project')
}
build.gradle file:dependencies {
compile group: 'groupId', name: 'artifactId', version: 'version'
}
Replace groupId, artifactId, and version with the appropriate values for the project you want to include.
libs directory of your project and adding the following to your build.gradle file:dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
}
Once you have added the other project as a dependency, you should be able to import its classes in your code using the import statement. For example:
import com.example.otherproject.MyClass;
You will also need to make sure that the other project is built and compiled before you can use its classes in your project. If you are using a build tool such as Gradle, this should happen automatically.
