“=” is assignment operator in JAVA language which assign the value of its right side to its left side value. The right side value can be of variable, constant orexpressionthat result some value and left side can be a variable or object which has the capacity to possess that right side ...
2. The instanceof operator can be used only to test objects (or null) against class types that are in the same class hierarchy. 3. For interfaces, an object passes the instanceof test if any of its superclasses implement the interface on the right side of the instanceof operator. 三. ...
there must be special methods. (You’ll find out later in this book that objects can be cast within a family of types; an Oak can be cast to a Tree and vice versa, but
A bitwise operatormanipulates individual bitsof its operands. Java defines several bitwise operators, which can be applied to the integer types,long,int,short,char, andbyte. 8. Ternary Operator Java has one conditional operator. It is called a ternary operator as it takesthree operands. The two...

The types of both operands must agree. Otherwise, the compiler will either use a widening conversion rule or report an error. The following code fragment demonstrates the simple assignment operator: String name = "Java Jeff"; Each compound assignment operator evaluates its left operand (which must...
Java Equality OperatorsThe == and != are equality operators of Java. The == operator returns true if its two operands are equal and false otherwise. When == operator is applied on primitive operands, it tests whether the operand values themselves are identical. For operands of reference types...

To better understand the “what” and the “how” about Kubernetes Operators, we need to understand the problem(s) that motivated the need for Kubernetes Operators. Kubernetes is notorious in its ability to integrate and facilitate declarative configuration and automation. This was out-of-the-box...
In the code example, we create a reference to a class and to a function with the double colon operator. val c = String::class c.supertypes.forEach { e -> println(e) } With the double colon operator, we refer to theStringclass. We print all its ancestors. ...
