當用戶輸入價值支付率時，它會檢查價值支付率與支付率數(shù)組。如果正確，那么它會提示用戶是否需要完成另一個過程。如果沒有，它將去計算。如果支付率錯誤，則顯示錯誤并要求用戶重新輸入值。我有問題，在用戶按下“Y”后，它會顯示“錯誤的支付率，請重試”。public static void main(String[] args) { //Scanner Scanner read = new Scanner(System.in); //Array of payRate Default double[] payRateDefault = {3.50, 4.00, 4.50, 4.75, 5.00, 5.25, 5.50, 5.75, 6.00}; double payRateEntered; boolean isPayRate = false; char anotherProcess; System.out.print("Enter hours work: "); int hoursWork = read.nextInt(); do { System.out.print("Enter pay rate: "); payRateEntered = read.nextDouble(); for (int i = 0; i < payRateDefault.length; i++) { if (payRateDefault[i] == payRateEntered) { //If the payRate is true with array payRateDefault, proceed to ask if you have another employee System.out.println("Do you have any employee to process (Y/N)"); anotherProcess = read.next().charAt(0); isPayRate = true; //Check if Y or N switch (anotherProcess) { case 'Y': //Proceed back to prompt user to enter pay rate break; case 'N': //Proceed to calculation break; default: //If wrong input System.out.println("Please use Y or N only"); break; } } else { isPayRate = false; } } System.out.println("You have entered the wrong pay rate. Please try again"); } while (!isPayRate);}結(jié)果：

以下代碼對我來說很好用：
package mm.com.java.so.test;
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
public class JavaRepeat {
public static void main(String[] args) throws IOException {
BufferedReader reader = new BufferedReader(new InputStreamReader(System.in));
double[] defaultPayRates = { 3.50, 4.00, 4.50, 4.75, 5.00, 5.25, 5.50, 5.75, 6.00 };
double payRate;
boolean isValid;
boolean isContinue;
String next;
int workingHour;
do {
isValid = false;
isContinue = false;
System.out.print("\nEnter hours work : ");
workingHour = Integer.parseInt(reader.readLine());
do {
System.out.print("Enter pay rate: ");
payRate = Double.parseDouble(reader.readLine());
for (int i = 0; i < defaultPayRates.length; i++) {
if (defaultPayRates[i] == payRate) {
isValid = true;
// TODO : make calculation here.
break;
}
}
if (!isValid) {
System.out.println("You have entered the wrong pay rate. Please try again !!!");
}
} while (!isValid);
do {
isValid = true;
System.out.println("\nDo you have any employee to process (Y/N)");
next = reader.readLine();
switch (next.toLowerCase()) {
case "y":
isContinue = true;
break;
case "n":
isContinue = false;
break;
default:
isValid = false;
System.out.println("Please use Y or N only.");
break;
}
} while (!isValid);
} while (isContinue);
// TODO : print out calculation here.
System.out.println("\nCalculation is doing. Please wait...");
}
}
我的測試結(jié)果如下：
Enter hours work : 3
Enter pay rate: 2
You have entered the wrong pay rate. Please try again !!!
Enter pay rate: 5
Do you have any employee to process (Y/N)
y
Enter hours work : 2
Enter pay rate: 5
Do you have any employee to process (Y/N)
z
Please use Y or N only.
Do you have any employee to process (Y/N)
N
Calculation is doing. Please wait...

僅當is時，您才應(yīng)該執(zhí)行該System.out.println("You have entered the wrong pay rate. Please try again");行。 isPayRatefalse
boolean finished = false;
do {
System.out.print("Enter pay rate: ");
payRateEntered = read.nextDouble();
for (int i = 0; i < payRateDefault.length; i++) {
if (payRateDefault[i] == payRateEntered) {
//If the payRate is true with array payRateDefault, proceed to ask if you have another employee
System.out.println("Do you have any employee to process (Y/N)");
anotherProcess = read.next().charAt(0);
isPayRate = true;
//Check if Y or N
switch (anotherProcess) {
case 'Y':
//Proceed back to prompt user to enter pay rate
break;
case 'N':
//Proceed to calculation
finished = true;
break;
default:
//If wrong input
System.out.println("Please use Y or N only");
break;
}
break;
} else {
isPayRate = false;
}
}
if (!isPayRate) {
System.out.println("You have entered the wrong pay rate. Please try again");
}
} while (!finished);
