โค้ดทีไ ่ ด้ import java.io.BufferedReader; import java.io.IOException; import java.io.InputStreamReader; public class TestArray1 { /** * @param args */ public static void main(String[] args) { BufferedReader datain = new BufferedReader(new InputStreamReader( System.in)); String animal = ""; System.out.println("Please write name animal :" + animal);

try {

animal = datain.readLine(); } catch (IOException e) { System.out.println("Error!"); } // Display the name System.out.println("Name is " + animal + "!"); String sex = ""; System.out.println("Please enter animal sex :" + sex); try { sex = datain.readLine(); } catch (IOException e) { System.out.println("Error!"); } // Display the name System.out.println("Sex is " + sex + "!"); System.out.println("Please Enter name animal :"); // Read entered data into age variable //try..catch is used for protection the program try { animal = datain.readLine(); } catch (IOException e) { System.out.println("Error!"); } // Display the name System.out.println("Name is " + animal + "!"); String sex1 = ""; System.out.println("Please enter animal sex :" + sex1); try { sex1 = datain.readLine(); } catch (IOException e) { System.out.println("Error!"); } // Display the name System.out.println("Sex is " + sex1 + "!"); } }

ผลลัพธ์ของโปรแกรม Please write name animal : Dog Name is Dog! Please enter animal sex : Male Sex is Male! Please Enter name animal : Cat Name is Cat! Please enter animal sex : Female

Sex is Female!

ข้อที2 ่

โค้ดทีด ่ ้ import java.io.BufferedReader; import java.io.IOException; import java.io.InputStreamReader; public class TestF3 { /** * @param args */ public static void main(String[] args) { BufferedReader datain = new BufferedReader(new InputStreamReader( System.in)); String Money = ""; System.out.println("Please your money is :" + Money); try { Money = datain.readLine(); } catch (IOException e) {

System.out.println("Error!"); } System.out.println("I have money is :" + Money + "Bath."); String Money1 = ""; System.out.println("What do you need ? " + Money1); try { Money1 = datain.readLine(); } catch (IOException e) { System.out.println("Error!"); } System.out.println("You need money is :" + Money1 + "Bath"); System.out.println("Thank you" + "!"); } }

ผลลัพธ์ของโปรแกรม Please your money is : 500 I have money is :500Bath. What do you need ? 400 You need money is :400Bath Thank you!

ข้อที3 ่

โค้ดทีไ ่ ด้ public class TestFor { /** * @param args */ public static void main(String[] args) { for (int count=0; count<=6; count++){ if (count!=5){ System.out.println(count); } else break; } System.out.println("End for"); } }

ผลลัพธืของโปรแกรม

0 1 2 3 4 End for
