Answer
Data types define the kind of data a variable can hold.
In Java, every variable must have a data type, which tells the compiler what kind of data to expect. This helps in memory allocation and ensures that operations on variables are type-safe. For instance, using 'int price = 100;' tells Java that 'price' will store integer values, preventing accidental use of non-integer operations.
