對於一個賦值,我應該讀取一個包含545個整數集的文本文件,每個集包含8個要存儲的整數一個對象「wayPoint」,每個整數有8個變量。從文本文件中讀取整數並將它們放入對象以存儲到散列圖
我想輸出我的結果來驗證,我確實已經加載到對象的整數,但控制檯輸出什麼。
我的課很粗糙,對於缺乏散文感到遺憾。
這是航點類:
public class Test {
public static void main(String args[])
{
System.out.println();
}
public void readwayPoints()
{
Scanner readFile = null;
try
{
readFile = new Scanner(new FileInputStream(
"insert text file here"));
}
catch(FileNotFoundException e)
{
System.out.println("File not found.");
System.exit(0);
}
int x = 0, y= 0, height = 0, cost = 0, gold = 0, mapX = 0, mapY = 0, neighbor = 0;
int count = 0;
List<Waypoint> list = new ArrayList<>();
while (readFile.hasNextLine())
{
x = readFile.nextInt();
y = readFile.nextInt();
height = readFile.nextInt();
cost = readFile.nextInt();
gold = readFile.nextInt();
mapX = readFile.nextInt();
mapY = readFile.nextInt();
neighbor = readFile.nextInt();
Waypoint wayP = new Waypoint(x, y, height, cost, gold, mapX, mapY, neighbor);
System.out.println(wayP);
list.add(wayP);
}
}
這裏是航點類:
public class Waypoint
{
private int x, y, height, cost, gold, mapX, mapY, neighbor;
public Waypoint (int x, int y, int height, int cost, int gold, int mapX, int mapY,
int neighbor)
{
this.x = x;
this.y = y;
this. height = height;
this.cost = cost;
this.gold = gold;
this.mapX = mapX;
this.mapY = mapY;
this.neighbor = neighbor;
}
public String toString()
{
return "x:" + this.x + "y:" + this.y + "height:" + this.height + "cost" + this.cost
+ "gold:" + this.gold + "mapX:" + this.mapX + "mapY:" + this.mapY + "neighbor"
+ this.neighbor;
}
}
}

你在循環結果並在每個航點上調用toString()嗎?另外java類通常以大寫開頭 – markg
