java 调用 perl_perl - Java调用perl

Runtime.getRuntime().exec("perl C:\\Perl\\execise.pl");

Java 调用 perl 通过IO的方式来得到返回值

package fiveGame;

import java.io.BufferedReader;

import java.io.IOException;

import java.io.InputStream;

import java.io.InputStreamReader;

public class JavaCallPerl {

public static void main(String[] args) throws IOException {

StringBuffer resultStringBuffer = new StringBuffer();

String lineToRead = "";

int exitValue = 0;

try {

Process proc = Runtime.getRuntime().exec("perl C:\\Perl\\execise.pl");

InputStream inputStream = proc.getInputStream();

BufferedReader bufferedRreader = new BufferedReader(new InputStreamReader(inputStream));

// save first line

if ((lineToRead = bufferedRreader.readLine()) != null) {

resultStringBuffer.append(lineToRead);

}

// save next lines

while ((lineToRead = bufferedRreader.readLine()) != null) {

resultStringBuffer.append("\r\n");

resultStringBuffer.append(lineToRead);

}

// Always reading STDOUT first, then STDERR, exitValue last

proc.waitFor(); // wait for reading STDOUT and STDERR over

exitValue = proc.exitValue();

} catch (Exception ex) {

resultStringBuffer = new StringBuffer("");

exitValue = 2;

}

System.out.println("exit:" + exitValue);

System.out.println(resultStringBuffer.toString());

}

}

perl

#!/usr/bin/perl -w

$pi = 3.141592654;

$circ = 2 * $pi * 12.5;

print "The circumference of a circle of radius 12.5 is $circ.\n";

请问调用perl时怎么传入参数？

我参考网上还有一种方式是：

String[] cmds = {"c:\\bin\\perl.exe","temp.pl","param1","param2"}

Process proc = Runtime.getRuntime().exec(cmds);

请问这2种方式有什么不一样？
