創建具有 10 個輸入的字符串類型的數組

Question

我想用數組練習，但我不明白為什么它不打印以下內容：問題是終端輸出：null 為什么會這樣，我做錯了什么？

package Practice;

public class CreatingArrays {
    public static void main(String[] args) {
        String[] women = { "persian", "palestinian", "german", "russian", "spanish", "italian", "greek", "hungarian",
                "brazilian", "turkish" };
        women = new String[10];

        System.out.println(women[8]);

    }
}

Answer 1

在打印到控制台之前，您正在將 women 重新分配為空字符串 [10]。 刪除women = new String[10]; 它應該工作正常。

Answer 2

String[] women = { "persian", "palestinian", "german", "russian",
"spanish", "italian", "greek", "hungarian","brazilian", "turkish" };

System.out.println(women[8]);

會為你工作。
