"jdeps class_file" - Dependencies of Class File

This section provides a tutorial example on how to use 'jdeps' command to show package level dependencies of a given Java class file.

If you want to know package level dependencies of a given Java class file, you can run the "jdeps class_file" command.

Let's use the ImportTestA.java program presented previous as an example:

/* ImportTestA.java
 * Copyright (c) HerongYang.com. All Rights Reserved.
import com.herongyang.util.*;
public class ImportTestA {
   public static void main(String[] arg){
      ClsA a = new ClsA();
      ClsB b = new ClsB();

Compile the program to get the Java class file:

herong> javac ImportTestA.java 

herong> dir 
    <DIR>          com
               404 ImportTestA.class
               292 ImportTestA.java

Run the "jdeps" command to show package level dependencies of the class file, ImportTestA.class:

herong> jdeps ImportTestA.class

ImportTestA.class -> java.base
ImportTestA.class -> not found
   <unnamed>      -> com.herongyang.util      not found
   <unnamed>      -> java.lang                java.base
