，但该怎么做？

i have an executable program (.exe) writen in c++ and run on windows console and i have a java swing applecation , so i want my java application to interact with the console app (send input and get output) . but how to do that ?

推荐答案

您可以这样做

// Create the proccess in JAVA
Process proc = Runtime.getRuntime().exec("Name of application");

// Receive outputs from another program inside Java by a stream
InputStream ips = proc.getInputStream();

// Using the stream to get the messages from another program
String output = "";
int c = 0;
while ((c = ips.read()) != -1){
    output+= (char)c;
}

//Inputs messages into another program
OutputStream ops = proc.getOutputStream();
ops.write("an byte array");
