A statement specifies an action in a Java program. For example, a statement may tell the add of values ofxandyand assign their sum to the variablez. It then prints a message to the standard output or writes data to a file, etc. Java statements can be broadly classified into three categ...
It’s probably good to begin by stating that since Groovy is based on Java, it has all of Java’s String capabilities like concatenation, the String API, and the inherent benefits of the String constant pool because of that. Let’s first see how Groovy extends some of these basics. ...

Every implementation of the Java programming language is required to support two standard sets of floating-point values, called the float value set and the double value set. In addition, an implementation of the Java programming language may support either or both of two extended-exponent floating...

As mentioned in The Diamond, because a Java compiler can infer the K and V types from the declaration OrderedPair<String, Integer>, these statements can be shortened using diamond notation: OrderedPair<String, Integer> p1 = new OrderedPair<>("Even", 8); OrderedPair<String, String> p2 = ...
