I am studying inner classes in Java.There is an example of using inner classes with different access modifiers.I wrote the code just I see in the book but I get an error which I have mentioned at the title.As I know we cant use a static variable,method in a non-static scope but what I dont understand is I get this error only with my String array.Integer array works fine.What am I missing here?
package innerclasses;
public class AlanlaraErisim {
private class StringDiziYaz{
private void diziYaz(String[]dizi){
for(String x: dizi){
System.out.println(x + " ");
}
}
}
protected class IntegerDiziYaz{
protected void diziYaz(Integer[]dizi){
for(Integer x: dizi){
System.out.println(x + " ");
}
}
}
public static void main(String[] args) {
AlanlaraErisim.StringDiziYaz stringDiziYaz = new AlanlaraErisim().new StringDiziYaz();
String[] stringDizi = {"abc","def","ghi","jkl","mno"};
StringDiziYaz.diziYaz(stringDizi); //Gives the error
AlanlaraErisim.IntegerDiziYaz integerDiziYaz = new AlanlaraErisim().new IntegerDiziYaz();
Integer[] intDizi = {1,2,3,4,5,6};
integerDiziYaz.diziYaz(intDizi); //Works fine
}}
Thats the output:
Exception in thread "main" java.lang.RuntimeException: Uncompilable source code - non-static method diziYaz(java.lang.String[]) cannot be referenced from a static context at innerclasses.AlanlaraErisim.main(AlanlaraErisim.java:42) /Users/sametsahin/Library/Caches/NetBeans/8.2/executor-snippets/run.xml:53: Java returned: 1 BUILD FAILED (total time: 1 second)
