java.lang.Runtime.getRuntime().exec(cmd)命令中参数不能用空格怎么办？

Question

项目中无法执行c程序，猜测是exec()函数的问题

String cmd= exe_path + " " +video + " " +host + ":" + port;
Process process = runtime.exec(cmd);

Answer 1

String[] cmd = new String[]{exe_path, video, host + ":" + port}

Answer 2

String[] cmd = {"/data/data/app_name/exename", "3" "ip:port"};
java.lang.ProcessBuilder builder = new java.lang.ProcessBuilder(cmd);
java.lang.Process process = builder.start();
int exitcode = process.waitFor();
