如何在其他应用程序中调用java文件？

我必须将java文件保存在同一个软件包dicomizer中：

*Pdf2Dcm.java：

    package dicomizer;

import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;

import java.util.Date;
import java.util.Enumeration;
import java.util.List;
import java.util.Properties;

import org.apache.commons.cli.GnuParser;
import org.apache.commons.cli.HelpFormatter;
import org.apache.commons.cli.OptionBuilder;
