在 java 代码中调用 c 程序

1.准备脚本 test.sh

2.编写代码

public class DemoTest {
public static void main(String[] args) {
String result=null;
String filePathOne="/home/one/test.pdf";
String filePathTwo="/home/two/test.pdf";
String fileId="123456";
StringBuffer sb =null;
String[] str=new String[4];
str[0]="/home/test/test.sh";
str[1]=filePathOne;//含有引号也需如此，若是"""+filePathOne+"""此种转义写法，会报错，原因不详。
str[2]=filePathTwo;
str[3]=fileId;
Process ps = null;
try {
ps = Runtime.getRuntime().exec(str);

        BufferedReader br = new BufferedReader(new InputStreamReader(
                ps.getInputStream()));

        sb = new StringBuffer(1024);
        String line;
        while ((line = br.readLine()) != null) {
            sb.append(line);
        }
        result = sb.toString();

        ps.waitFor();

    } catch (Exception e) {
        result = "-1";
    }
    finally
    {
        if(ps != null)
        {
            try {
                ps.getInputStream().close();
                ps.getErrorStream().close();
                ps.getOutputStream().close();
            } catch (IOException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
            ps.destroy();
        }
    }
}

}
