只有在通過java完成進程后，我的代碼才會繼續

Question

我正在通過一個進程運行exec命令。 我希望我的程序只在進程完成后才會繼續運行。 這是我的代碼：

Runtime runtime = Runtime.getRuntime();
Process process = runtime.exec("tools/jadx/bin/jadx.bat -d JavaProjects/");

//the rest of the code
System.out.println("Process is finished");

我需要其余的代碼只在進程完成后執行，因為它取決於進程輸出。 有任何想法嗎？

Answer 1

我有答案，現在它有效！

Eevery流程具有輸入和輸出流。 我的具體過程必須清空他的輸入緩沖區才能繼續運行。 我添加的是以下代碼：

Runtime runtime = Runtime.getRuntime();
Process process = runtime.exec("tools/jadx/bin/jadx.bat -d JavaProjects/");
out = new BufferedWriter(new OutputStreamWriter(process.getOutputStream()));
in = new BufferedReader(new InputStreamReader(process.getInputStream()));
String line;
while ((line = in.readLine()) != null) {
    System.out.println(line);
}
int lExitCode = process.waitFor();
if (lExitCode == 0)
    System.out.println("\n\n$$$$$   Process was finished successfully   $$$$$\n\n");
else
    System.out.println("\n\n$$$$$   Process was finished not successfully   $$$$$\n\n");

Answer 2

waitFor就是為了這個目的：

Runtime runtime = Runtime.getRuntime();
Process process = runtime.exec("tools/jadx/bin/jadx.bat -d JavaProjects/");
int lExitCode = process.waitFor();
//the rest of the code
if (lExitCode == 0)
  System.out.println("Process was finished successfull.");
else
  System.out.println("Process was finished not successfull.");
