JAVA計時器(秒表)程序代碼(最新整理)

1、java 計時器（秒表）功能：能實現(xiàn)計時，暫停，清零，記錄功能。如下圖：程序運行狀態(tài)：源代碼：import javax.swing.*; import java.awt.*; import java.awt.event.*; public class test public static void main(string args)new window(計時器);class window extends jframeint on=0,i=0,j=0,k=0,count=0,num=1,r=0;jbutton button1,button2,button3,button4,button5; jt

2、extfield file1,file2,file3;jtextarea file; flowlayout flow; string a,b,c; window(string name)file1=new jtextfield(2); file2=new jtextfield(2); file3=new jtextfield(2); file1.seteditable(false); file2.seteditable(false); file3.seteditable(false); file=new jtextarea(10,8); file.seteditable(false); but

3、ton1=new jbutton(開始);button2=new jbutton(暫停);button3=new jbutton(清零); button4=new jbutton(記錄);button5=new jbutton(清空記錄); flow=new flowlayout(); flow.setalignment(flowlayout.left); flow.sethgap(20);flow.setvgap(10); settitle(name); setsize(210,400); setlayout(flow); add(file1);add(new jlabel(:); add(

4、file2);add(new jlabel(:); add(file3); add(button1); add(button2); add(button3); add(button4); add(button5); add(file); setvisible(true);setdefaultcloseoperation(exit_on_close); file1.settext(0);file2.settext(0);file3.settext(0); validate();button1.addactionlistener(new actionlistener() public void a

5、ctionperformed(actionevent e) on=1; /開始，暫停控制開關(guān)); /開始按鈕button2.addactionlistener(new actionlistener() public void actionperformed(actionevent e) on=0;); /暫停按鈕button3.addactionlistener(new actionlistener() public void actionperformed(actionevent e) r=1; /清零控制開關(guān)); /清零按鈕button4.addactionlistener(new act

6、ionlistener() public void actionperformed(actionevent e)count=1; /記錄控制開關(guān)a=string.valueof(i); b=string.valueof(j); c=string.valueof(k);); /記錄按鈕button5.addactionlistener(new actionlistener() public void actionperformed(actionevent e)file.settext(); num=1;); /清除記錄按鈕while(true)validate();if(on=1) /開始或暫停

7、判斷file1.settext(string.valueof(i); file2.settext(string.valueof(j); file3.settext(string.valueof(k); if(k=99)k=-1; j+;if(j=60)k=0; j=0; i+;if(i=24)i=0; j=0; k=0;trythread.sleep(10);catch(exception e) k+;if(count=1)/記錄判斷file.append(string.valueof(num); file.append(. ); file.append(a); file.append(:);

8、 file.append(b); file.append(:); file.append(c); file.append(n);num+; count=0;if(r=1)/清零判斷i=j=k=0; file1.settext(string.valueof(i); file2.settext(string.valueof(j); file3.settext(string.valueof(k);r=0;“”“”at the end, xiao bian gives you a passage. minand once said, people who learn to learn are very

9、 happy people. in every wonderful life, learning is an eternal theme. as a professional clerical and teaching position, i understand the importance of continuous learning, life is diligent, nothing can be gained, only continuous learning can achieve better self. only by constantly learning and mastering the latest relevant knowledge, can employees from all walks of life keep up with the pace of enterprise development and innovate to meet the needs of the
