Question

由于文件夹名称中有括号，此代码失败。 Java Runtime exec无法正确解析文件位置。您有任何建议如何解决这个问题吗？

import java.io.IOException;

public class SampObject {

    String command;

    public void launchBatch() {
        String cmdArray[];

        command = "C:\\test(1)folder\\Launch.bat";

        cmdArray = new String[] {
            "cmd",
            "/c",
            "start",
            command
        };

        try {
            Runtime.getRuntime().exec(cmdArray);
            System.out.println("Batch file launched");
        } catch (IOException e) {
            System.out.println("Error launching file: " + e.toString());
        }
    }
}

公共类示例{

public static void main(String[] args) {
    SampObject sampObj = new SampObject();
    sampObj.launchBatch();
}

}
