Java is a strongly typed programming language because every variable must be declared with a data type. A variable cannot start off life without knowing the range of values it can hold, and once it is declared, the data type of the variable cannot change.


The following declaration is allowed because the variable has "hasDataType" is declared to be a boolean data type:

boolean hasDataType;

For the rest of its life, hasDataType can only ever have a value of true or false.
