What is a NullPointerException, and how do I fix it? (12 个回答)

这是我的代码。输出应该是 32.9。但似乎显示

Exception in thread "main" java.lang.NullPointerException at ArrayLocation.main(ArrayLocation.java:14)

<小时/>

public class ArrayLocation {
    private double coords[];

    public ArrayLocation(double[] coods){
        this.coords=coords;
    }

    public static void main(String[] args){
        double[] coords={5.0,0.0};
        ArrayLocation accra= new ArrayLocation(coords);
        coords[0]=32.9;
        coords[1]=-117.2;
        System.out.println(accra.coords[0]);
    }
}

Answer 1

您的代码中有一个拼写错误。

改变

public ArrayLocation(double[] coods) {

至

public ArrayLocation(double[] coords) {
