编译语言-简单的单词识别程序

实验一简单的单词识别程序一、实验内容设计一个识别单词的程序，从文本文件中读取字符串，将字符串中的字符根据空格逐个识别为单词，并比较单词是否为zero ， one ， two ， three ， four ，five ， six， seven ， eight ， nine ，若是则输出该单词对应的阿拉伯数字。要求用java 语言、图形界面方式编程。（可参考实验指导书p110 至 p113 ）举例：若文本文件中的字符串为one at are three six 234 eight则输出为1368二、程序代码distinguishword.javapackagezlf;import java.io.*;import java.awt.*;import java.awt.event.*;import javax.swing.*;public class distinguishwordextendsjappletprivate jfilechooser jfc =new jfilechooser(new file(.);private jtextarea jta1 =new jtextarea();private jtextarea jta2 =new jtextarea();private jbutton jlb1 =new jbutton( 字符串的内容为：);private jbutton jlb2 =new jbutton( 其中英文对应的阿拉伯数字为：); private jlabel filename =new jlabel( filename );精品资料private jtextfieldjtf = new jtextfield(30);private jbutton brower =new jbutton(brower);public distinguishword()jpanel p1 =new jpanel();p1.setlayout(new borderlayout();p1.setborder(borderfactory.createemptyborder (5,5,5,10); p1.add(jlb1,borderlayout.north );p1.add( new jscrollpane(jta1), borderlayout.center ); add(p1,borderlayout.center );jpanel p2 =new jpanel();p2.setlayout(new borderlayout();p2.setborder(borderfactory.createemptyborder (5,5,5,10); p2.add(jlb2,borderlayout.north );p2.add( new jscrollpane(jta2), borderlayout.center );add(p2,borderlayout.east );jpanel p3 =new jpanel();p3.setlayout(new borderlayout();p3.add(filename,borderlayout.west ); p3.add(jtf);p3.add(brower, borderlayout.east );add(p3,borderlayout.south ); jtf.settext(c:/1.txt);brower.addactionlistener(new actionlistener()public void actionperformed(actionevent e)open(););jtf.addkeylistener(new keyadapter()public void keypressed(keyevent e)if(e.getkeychar()=keyevent.vk_enter )/按回车键执行相应操作;string file = jtf.gettext();try bufferedinputstream in =new bufferedinputstream(newfileinputstream(file);byte b = new byte in.available();in.read(b,0,b.length);jta1.append(new string(b,0,b.length);in.close(); catch (ioexception e1) jta1.settext(error opening ););jlb2.addactionlistener(new actionlistener()public void actionperformed(actionevent e)string s = jta1.gettext();jta2.settext(translatefigure(s););private string translatefigure(string string)string english = zero,one,two,three,four,five,six,seven,eight,nine;string s = string;string str = ;string t = ;int n = 0;char ch = s.tochararray();for (int i = 0; i s.length(); i+)if(chi = |chi = .|chi = ， ) t = s.substring(n, i);n = i+1;for ( int j = 0; j 10; j+)if(t.equals(englishj)str = str + j;return str;private void open()if(jfc.showopendialog(this ) = jfilechooser.approve_option ) open(jfc.getselectedfile();private void open(file file)trybufferedinputstream in =new bufferedinputstream(new fileinputstream(file);byte b = new byte in.available();in.read(b,0,b.length);jta1.append(new string(b,0,b.length);in.close();jtf.settext(file.getname();catch (ioexception ex)jtf.settext(error opening + file.getname();1.txtone at are three six 234 eight三、实验结果截图：简单说明：字符串内容框内可输入内容，点击“其中英文对应的阿拉伯数字为：”按钮可得出结果，或者在filename后输入文件路径与文件名后回车，字符串内容框会显示文本文件内容，此时再点击“其中英文对应的阿拉伯数字为：”按钮可得出结果， 或者在“brower ”按钮查找文件显示在
