[英]Creating an Array of type String with 10 inputs
I wanted to practice with array and I don't get why it doesn't print the following out: The problem is that the terminal outputs: null Why is that and what did I do wrong?我想用数组练习,但我不明白为什么它不打印以下内容:问题是终端输出:null 为什么会这样,我做错了什么?
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]);
}
}
You are re-assigning women to be an empty string[10] before printing to console.在打印到控制台之前,您正在将 women 重新分配为空字符串 [10]。 Remove women = new String[10];
删除women = new String[10];
and it should work fine.它应该工作正常。
String[] women = { "persian", "palestinian", "german", "russian",
"spanish", "italian", "greek", "hungarian","brazilian", "turkish" };
System.out.println(women[8]);
Will work for you.会为你工作。
