将变量传递给Java进程

Question

I am not sure if this is possible but does anyone know if it possible to pass a variable to a java process? 我不确定这是否可行，但是有人知道是否可以将变量传递给Java进程吗？

My code is: 我的代码是：

Process process = Runtime.getRuntime().exec("cmd /c *curl command* -o "file.png");

And I want to do look something like: 我想看起来像：

int X = 0;

Process process = Runtime.getRuntime().exec("cmd /c *curl command* -o "fileX.png");

X++;

This way I can have output like: 这样，我可以有如下输出：

file0.png

file1.png

file2.png

Any help would be great. 任何帮助都会很棒。 Thanks in advance. 提前致谢。

You're essentially building a string. 您实质上是在构建字符串。

for (int x=0;x<MAX;x++){
    String command = "cmd /c curl command -o \"file" + x + ".png\"";
    // use it!
}
