Where to see the source code for Java library?

If you have no tool, you can write your own tool:
import java.util.zip.*;
import java.io.*;
public class ZipTest {
     public static void main(String[] args) {
          if(args.length != 2) {
               System.err.println("using: java ZipTest [zip file] [target directory]");
               System.exit(1);
          String sourceFilename  = args[0];
          String targetDirectory = args[1];
          new ZipTest().unzip(sourceFilename, targetDirectory);
     public void unzip(String sourceFilename, String targetDirectory) {
          String fileSeparator = System.getProperty("file.separator");
          if(! targetDirectory.endsWith(fileSeparator)) {
               targetDirectory += fileSeparator;
          try {
               ZipFile zipFile = new ZipFile(sourceFilename);
               java.util.Enumeration entries = zipFile.entries();
               while(entries.hasMoreElements()) {
                    ZipEntry entry = (ZipEntry)entries.nextElement();
                    if(entry.isDirectory()) {
                         continue;
                    String name = entry.getName();
                    name = targetDirectory + name;
                    System.out.println(name);
                    File file = new File(name);
                    File directory = file.getParentFile();
                    if(! directory.exists()) {
                         directory.mkdirs();
                    BufferedInputStream bis = new BufferedInputStream(
                         zipFile.getInputStream(entry));
                    BufferedOutputStream bos = new BufferedOutputStream(
                         new FileOutputStream(file));
                    byte[] b = new byte[1024];
                    int count = 0;
                    while((count = bis.read(b, 0, 1024)) != -1) {
                         bos.write(b, 0, count);
                    bis.close();
                    bos.close();
               zipFile.close();
          } catch(java.io.IOException e) {
               System.err.println(e);
}
