在Java中使用RPM進行軟件包管理并不常見，因為RPM通常用于Linux系統上的軟件包管理。如果您想在Java中使用RPM進行軟件包管理，您可以借助Java庫來調用系統命令來執行RPM相關操作。

以下是一個示例，展示如何使用Java調用系統命令來安裝、卸載和查詢RPM軟件包：

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;

public class RPMManager {
    
    public static void installPackage(String packageName) {
        try {
            Process process = Runtime.getRuntime().exec("sudo rpm -i " + packageName);
            BufferedReader reader = new BufferedReader(new InputStreamReader(process.getInputStream()));
            String line;
            while ((line = reader.readLine()) != null) {
                System.out.println(line);
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
    
    public static void uninstallPackage(String packageName) {
        try {
            Process process = Runtime.getRuntime().exec("sudo rpm -e " + packageName);
            BufferedReader reader = new BufferedReader(new InputStreamReader(process.getInputStream()));
            String line;
            while ((line = reader.readLine()) != null) {
                System.out.println(line);
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
    
    public static void queryPackage(String packageName) {
        try {
            Process process = Runtime.getRuntime().exec("rpm -q " + packageName);
            BufferedReader reader = new BufferedReader(new InputStreamReader(process.getInputStream()));
            String line;
            while ((line = reader.readLine()) != null) {
                System.out.println(line);
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
    
    public static void main(String[] args) {
        installPackage("example-package.rpm");
        queryPackage("example-package");
        uninstallPackage("example-package");
    }
}

請注意，上述代碼中調用了系統命令，需要在Java程序的運行環境中確保有足夠的權限來執行這些命令。另外，要確保正確安裝了RPM軟件包管理工具。
