Variables In Java | Java For Beginers | Not A Coder @NotACoder1999 смотреть онлайн

int is a primitive data type that represents whole numbers. In Java, int variables are 32 bits long, which allows them to represent values between -2,147,483,648 and 2,147,483,647.

double is a primitive data type that represents double-precision floating-point numbers. In Java, double variables are 64 bits long, which allows them to represent decimal values with high precision.

float is a primitive data type that represents single-precision floating-point numbers. In Java, float variables are 32 bits long, which allows them to represent decimal values with moderate precision.

String is a class in Java that represents a sequence of characters. In Java, String variables are immutable, meaning they cannot be changed once they are created. Strings are commonly used for storing and manipulating text data.

It is important to choose the appropriate data type for each variable, depending on the range and precision of values that need to be stored. Using a data type that is too small can result in values being truncated or losing precision, while using a data type that is too large can waste memory.
