使用Java执行CMD命令可以通过以下步骤实现:
Runtime
类获取运行时对象:Runtime runtime = Runtime.getRuntime();
runtime.exec()
方法执行CMD命令:Process process = runtime.exec("cmd /c <your_command>");
其中,<your_command>
是你要执行的CMD命令。
process.getInputStream()
获取命令执行的输出结果:InputStream inputStream = process.getInputStream();
BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream));
String line;
while ((line = reader.readLine()) != null) {
System.out.println(line);
}
process.getErrorStream()
获取命令执行的错误信息:InputStream errorStream = process.getErrorStream();
BufferedReader errorReader = new BufferedReader(new InputStreamReader(errorStream));
String errorLine;
while ((errorLine = errorReader.readLine()) != null) {
System.out.println(errorLine);
}
process.waitFor()
等待命令执行完成:int exitCode = process.waitFor();
System.out.println("Command executed with exit code: " + exitCode);
完整的Java代码示例:
import java.io.BufferedReader;
import java.io.InputStream;
import java.io.InputStreamReader;
public class ExecuteCMD {
public static void main(String[] args) {
try {
Runtime runtime = Runtime.getRuntime();
Process process = runtime.exec("cmd /c <your_command>");
InputStream inputStream = process.getInputStream();
BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream));
String line;
while ((line = reader.readLine()) != null) {
System.out.println(line);
}
InputStream errorStream = process.getErrorStream();
BufferedReader errorReader = new BufferedReader(new InputStreamReader(errorStream));
String errorLine;
while ((errorLine = errorReader.readLine()) != null) {
System.out.println(errorLine);
}
int exitCode = process.waitFor();
System.out.println("Command executed with exit code: " + exitCode);
} catch (Exception e) {
e.printStackTrace();
}
}
}
