In Java, a strongly typed language refers to a language that enforces strict type-checking at compile-time. It ensures that variables and expressions are used in a manner consistent with their declared types. This means that every variable must have a declared type, and the type is checked at compile-time to prevent any incompatible operations or assignments.
Java is often cited as a strongly typed language because of its robust type system. When you declare a variable in Java, you must specify its type explicitly. For example, you might declare an integer variable as follows:
int num = 10;
Here, the variable num is explicitly declared as an integer. Java will only allow operations and assignments that are valid for integers to be performed on this variable. If you try to assign a value of a different type or perform an incompatible operation, the Java compiler will generate an error.

The benefits of a strongly typed language like Java include improved reliability and early error detection. By catching type-related errors at compile-time, the Java compiler helps to prevent many runtime errors that could occur otherwise. This reduces the likelihood of unexpected behavior or crashes in a Java program.
Additionally, strong typing provides improved code readability and maintainability. By explicitly declaring variable types, it becomes easier for developers to understand the intent and usage of variables within the codebase. This can also facilitate collaboration between team members and make the code easier to maintain and debug.
Java achieves strong typing through its static type-checking mechanism. The Java compiler analyzes the code during the compilation process and verifies that the operations and assignments are type-compatible. It performs a series of checks, such as verifying that the operands of an arithmetic operation are of numeric types or that method calls are made on objects of appropriate types.

In contrast to strongly typed languages, dynamically typed languages like Python or JavaScript do not perform strict type checking at compile-time. Instead, they determine the types of variables and expressions at runtime. This allows for more flexibility but can also lead to potential type-related issues that may only surface during program execution.
It is worth mentioning that while Java is considered a strongly typed language, it also incorporates some aspects of type flexibility through mechanisms such as type casting and polymorphism. Type casting allows you to convert a variable from one type to another, provided that the conversion is valid. Polymorphism enables objects of different types to be treated as instances of a common superclass or interface, allowing for more flexibility in code design.
In conclusion, a strongly typed language like Java enforces strict type-checking at compile-time, requiring explicit type declarations and preventing incompatible operations and assignments. This approach improves program reliability, readability, and maintainability by catching type-related errors early on and facilitating better code understanding. Java's strong typing, coupled with features like type casting and polymorphism, strikes a balance between type safety and flexibility.
