錯誤：不兼容的類型：int []不能轉換爲int

-2

我正在一個項目上工作，我不斷地收到錯誤消息說錯誤：當試圖編譯時，incompatible types int []不能轉換爲int。錯誤說它是在第17行。我試圖改變一切雙打，我得到同樣的錯誤雙打。我不知道爲什麼這些數字無法存儲，解釋會很有幫助。錯誤：不兼容的類型：int []不能轉換爲int

int[][] houseNumbers; 
    int numberOfHouses, homeNumber, numberOfPeople, house, people; 
    System.out.print("How many houses in the street?: "); 
    numberOfHouses = keyboard.nextInt(); 
    houseNumbers = new int[numberOfHouses][]; 
    for (house = 0; house < houseNumbers.length; house++){ 
     System.out.print("What is the next house number? : "); 
     houseNumbers[house] = keyboard.nextInt(); 
     System.out.print("How many people live in house number" + houseNumbers[house] + ":"); 
     numberOfPeople = keyboard.nextInt(); 
     houseNumbers[house] = new int[numberOfPeople]; 
     for (people = 0; people < houseNumbers[house].length; people++){ 
      System.out.print("What is the age of person " + people + ": "); 
      houseNumbers[house][people] = keyboard.nextInt(); 
     } 
    }

'houseNumbers [房子] = keyboard.nextInt（）;'分配一個'int'到'int'陣列。三行後，你做得正確。你可能想'numberOfPeople = keyboard.nextInt（）;'那裏。 –

所以我做了：homeNumber = keyboard.nextInt（）; houseNumbers [house] = homeNumber;並且我仍然得到相同的錯誤 – Mark

將int分配給int數組有什麼問題？ – Mark

你有幾個錯誤。最大的嘗試是將int分配給int陣列。數組是一個（一個或多個）項目的塊。您必須先分配new塊，然後才能訪問各個項目。你的編譯器告訴你這一點。學習理解編譯器的錯誤和警告。

錯誤1：

/* houseNumbers[house] -> */ homeNumber = keyboard.nextInt();

錯誤2：

System.out.print("How many people live in house number" + /* houseNumbers[house] -> */ homeNumber + ":");
