[英]Lonely Integer - Output is correct. But still getting additional message
我試圖在數組中找到孤獨的整數。 我的輸出是正確的,但仍然收到額外的消息。 請看一下代碼。 我正在使用Java編寫程序。
碼:
import java.util.InputMismatchException;
import java.util.Scanner;
public class LonelyInteger {
private static int inputArray[];
private static int inputLength;
private static final Scanner scanner = new Scanner(System.in);;
public static void main(String[] args) {
try {
if (getInput()) {
sortAndPrintArray();
findLonelyInteger();
} else {
System.out.println("OOPS, something is not right! Try again!");
}
} catch (NumberFormatException | InputMismatchException nfime) {
System.out.print("Number Format Exception or Input Mismatch Exception Occured: " + nfime);
} catch (Exception e) {
System.out.print("Exception Occured: " + e.getMessage());
}
}
private static boolean getInput() throws NumberFormatException, InputMismatchException, Exception {
System.out.print("Enter the array length: ");
inputLength = scanner.nextInt();
if (inputLength <= 0) {
return false;
}
inputArray = new int[inputLength];
System.out.println("Enter the array:");
for (int i = 0; i < inputLength; i++) {
inputArray[i] = scanner.nextInt();
}
return true;
}
private static void sortAndPrintArray() {
sortArray();
printSortedArray();
}
private static void sortArray() {
int temp = 0;
for (int i = 0; i < inputLength; i++) {
for (int j = 0; j < i; j++) {
if (inputArray[i] < inputArray[j]) {
temp = inputArray[i];
inputArray[i] = inputArray[j];
inputArray[j] = temp;
}
}
}
}
private static void printSortedArray() {
System.out.println("Sorted Array:");
for (int i = 0; i < inputLength; i++) {
System.out.print(inputArray[i] + " ");
}
System.out.println();
}
private static void findLonelyInteger() {
boolean foundLonelyInteger = false;
for (int i = 0; i < inputLength; i++) {
if ((i+1) == inputLength) {
System.out.println("Lonely Integer: " + inputArray[i]);
break;
}
if (inputArray[i] == inputArray[++i]) {
continue;
} else {
System.out.println("Lonely Integer: " + inputArray[i-1]);
foundLonelyInteger = true;
i--;
}
}
if (!foundLonelyInteger) {
System.out.println("Lonely integer not available!");
}
}
}
這是我的輸出,在命令提示符中可以看到:
輸出:
Enter the array length: 5
Enter the array:
1
2
2
1
2
Sorted Array:
1 1 2 2 2
Lonely Integer: 2
Lonely integer not available!
您沒有在findLonelyInteger()
方法的第一個if
條件中設置標志!
if ((i+1) == inputLength) {
System.out.println("Lonely Integer: " + inputArray[i]);
foundLonelyInteger = true; // --> HERE
break;
}
命令提示符? 開始使用Eclipse! 並學習調試!
設置您的foundLonelyInteger = true;
在檢查if((i+1) == inputLength)
