Here is a common method for traversing a HashMap in Java: Using keySet() and forEach(): You can use the keySet() method to obtain a set of all the keys in the HashMap. Then, you can use the forEach() method to iterate over the keys and perform actions on the corresponding ...
@SuppressWarnings("unchecked") is an annotation in Java that tells the compiler to suppress specific warnings that are generated during the compilation of the code. The unchecked warning is issued by the compiler when a type safety check has been suppressed, typically using an @SuppressWarnings("...
The extent to which a programming language discourages or prevents type error is known as type safety. When a programming language requires a variable to be used only in ways that respect its data type, that language is said to bestrongly typed. If data types do not align -- such as try...

It is not necessary that the set of constants in an enum type stay fixed for all time. Enum in Java provides type-safety and can be used when we know all possible values at compile time. Since enum is a keyword you can not use as variable name and since its only introduced in JDK ...
DataFrames:DataFrames organise data into columns for SQL operations. These do not provide data type safety, although that is covered in datasets themselves. Datasets:Datasets also organise data into columns for SQL queries. They do provide data type safety measures. ...
