Issues filling an array in Java
问题
以下是您要翻译的代码部分：
private static int read(String inFileName, int[] list) {
int size = 0;
int i = 0;
Scanner inFile = null;
int val = 0;
int trash = 0;
boolean ID = false;
int Unique = 0;
int dupe = 0;
int lineCount = 0;
try {
inFile = new Scanner(new File(inFileName));
while (inFile.hasNext()){
lineCount++;
try{
val = inFile.nextInt();
if(val < 0) {
trash++;
continue;
}
for(i = 0; i< size ;i++){
if(list[i] == val){
ID = true;
dupe++;
}
}
if (ID == false && size<list.length){
list[size] = val;
size++;
Unique++;
}
}
catch (InputMismatchException e){
trash++;
inFile.nextLine();
}
}
System.out.println("lines: " + lineCount + ", unique: " + Unique + ", dupes: " + dupe + ", trash: " + trash);
}
catch (FileNotFoundException e) {
System.out.println("Error in opening " + inFileName);
}
return size;
}

英文:
I am trying to fill an array with the unique values from another file. This file has about 20 integers total, 10 are unique and 10 are copies. The user inputs the size of the array and name of the file within the main.
I think the trouble is coming from this while loop that is meant to fill the array, sorting out the duplicates.
At the moment, it only successfully sorts 11 of the 20 integers in the file.
private static int read(String inFileName, int[] list) {
int size = 0;
int i= 0;
Scanner inFile = null;
int val = 0;
int trash = 0;
boolean ID = false;
int Unique = 0;
int dupe = 0;
int lineCount = 0;
try {
inFile = new Scanner(new File(inFileName));
while (inFile.hasNext()){
lineCount++;
try{
val = inFile.nextInt();
if(val < 0) {
trash++;
continue;
}
for(i = 0; i< size ;i++){
if(list[i] == val){
ID = true;
dupe++;
}
}
if (ID == false && size<list.length){
list[size] = val;
size++;
Unique++;
}
}
catch (InputMismatchException e){
trash++;
inFile.nextLine();
}
}
System.out.println("lines: " + lineCount + ", unique: " + Unique + ", dupes: " + dupe + ", trash: " + trash);
}
catch (FileNotFoundException e) {
System.out.println("Error in opening " + inFileName);
}
return size;
}
So far, I have tried adding different if-statements to try and specify what is unique and what is a copy. This would typically help in filling the array with the correct number of integers, but not the unique ones. It seems to be skipping quite a few unique integers and filling the array with copies. I am pretty stuck, and any suggestions whatsoever would be appreciated.

我已经完成了代码的翻译，以下是翻译好的部分：
// 评论了你的代码后，你进行了更改，然后应该可以工作。
private static int read(String inFileName, int[] list) {
int size = 0;
int i = 0;
Scanner inFile = null;
int val = 0;
int trash = 0;
// boolean ID = false; 移除
int Unique = 0;
int dupe = 0;
int lineCount = 0;
try {
inFile = new Scanner(new File(inFileName));
while (inFile.hasNext()) {
boolean ID = false; // 在这里添加
lineCount++;
try {
val = inFile.nextInt();
if (val < 0) {
trash++;
continue;
}
for (i = 0; i < size; i++) {
if (list[i] == val) {
ID = true;
dupe++;
}
}
if (ID == false && size < list.length) {
list[size] = val;
size++;
Unique++;
}
} catch (InputMismatchException e) {
trash++;
inFile.nextLine();
}
}
System.out.println("lines: " + lineCount + ", unique: " + Unique + ", dupes: " + dupe + ", trash: " + trash);
} catch (FileNotFoundException e) {
System.out.println("Error in opening " + inFileName);
}
return size;
}
