I have three files, as shown below. When I run code inspection, it suggests
that joe.klyde can be static: "Does not use context instance fields or calls
context instance methods and therefore can have static modifier. " However,
joe.klyde can not be made static in this case. If I make it static, the
compiler reports: "Error: line (11) non-static variable this cannot be
referenced from a static context".
-----test.java-----
class test
{
public static void main( String[] args )
{
System.out.println( new joe() );
}
}
------(EOF)------
-----fred.java-----
class fred
{
private int fTotal = 0;
fred() { fTotal++; }
class Attributes
{
private final String fString = "hello" + fTotal;
public String toString()
{
return fString;
}
}
}
------(EOF)------
-----joe.java-----
class joe extends fred
{
public String toString()
{
return "joe: " + new klyde();
}
private class klyde
{
private final Object fAttrs = new fred.Attributes();
public String toString()
{
return fAttrs.toString();
}
}
}
------(EOF)------
