Use of thestaticKeyword Along With Member Variables in Java The code block explains how the static variable is different from non-static variables. publicclassStaticVariableUsage{publicstaticvoidmain(String[]args){InnerClass in=newInnerClass();InnerClass in1=newInnerClass();InnerClass2 in2=newInne...
It is generally a convention to put the access specifier (i.epublic,privateorprotected) in the beginning of the method declaration or definition. You can understand the meaning ofpublic,staticandvoidkeywords as follows. public: It is an access specifier, which defines who c...
void method2(){} } } In the example above we have Donna and Red both nested classes of Eric. Remember Eric is the top level class so it can’t be made static. So, that leaves us with Donna and Red. Eric is in love with Donna, meaning it would be wise of us to make Donna st...
public class test {public static void main(String [] args) { int x = 3; int y = 1; if (x = y) System.out.println("Not equal"); else System.out.println("Equal");}}What is the result? A. The output is揈qual?br> B. The output in揘ot Equal?br> C. An error at " if...
You are forced to implement an interface without much semantic meaning. We can still do better than this. 3. Use Java static imports Static imports are introduced in Java 5. Using static imports you can import static members/properties of a class so that you can directly access them without...
public class Program { public void static main(String[] args) { System.out.println("hi"); } } this gives an error while public class Program { public s
introducing a new keyword. Finally, C++ reused the keyword for a third, unrelated, interpretation—to denote variables and functions that belong to a class but not to any particular object of the class. That is the same meaning the keyword has in Java. ...

One reason to think that it may have been deliberate is that it makes it very easy for an interpreter to look up the meaning of a name: all that is required is a stack of declarations (we examine this stack more closely in Section 3.4.2). Unfortunately, this simple implementation has ...
public static void main( String[] args ) { ST_Employee se1 = new ST_Employee(); se1.eid = 104; se1.name = "Abhijit"; se1.show(); } } Q. Why a non-static variable cannot be referenced from a static context ? This is because non-static variables are related with instance of ...
