二、使用案例
使用Runtime的例子
package net.java2000.util;
import java.io.BufferedReader;
import java.io.File;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.util.Arrays;
public class TestRuntime {
/**
* @param args
* @throws Exception
*/
public static void main(String[] args) throws Exception {
Runtime runtime = Runtime.getRuntime();
Process process = runtime.exec("cmd /c dir",null,new File("e:/"));
InputStream is = process.getInputStream();
InputStreamReader isr = new InputStreamReader(is,"GBK");
BufferedReader br = new BufferedReader(isr);
String line;
System.out.printf("Output of running %s is:", Arrays.toString(args));
while ((line = br.readLine()) != null) {
System.out.println(line);
}
}
}
使用ProcessBuilder的例子
package net.java2000.util;
import java.io.BufferedReader;
import java.io.File;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.util.Arrays;
public class TestProcessBuilder {
public static void main(String args[]) throws Exception {
ProcessBuilder builder = new ProcessBuilder("cmd", "/c", "dir");
builder.directory(new File("e:/"));
Process process = builder.start();
InputStream is = process.getInputStream();
InputStreamReader isr = new InputStreamReader(is, "GBK");
BufferedReader br = new BufferedReader(isr);
String line;
System.out.printf("Output of running %s is:", Arrays.toString(args));
while ((line = br.readLine()) != null) {
System.out.println(line);
}
}
}
