Golang Java
Go is a procedural and concurrent programming language.Java is an Object-Oriented programming language.
Golang does not support classes with constructors and deconstructors.Java supports classes with constructors and deconstructors.
Golang does not contain the concept of exception handling instead of exception handling Go has errors.Java contains the concept of exception handling.
Golang does not support implicit type conversion.Java supports implicit type conversion. This happens when the two data types are compatible and also when we assign the value of a smaller data type to a larger data type.
Golang does not support inheritance.Java supports inheritance. It is possible to inherit attributes and methods from one class (parent) to another (child).
Golang supports Goroutine. It is a lightweight thread managed by the Go runtime.Java does not support Goroutines.
Golang does not support function overloading.Java supports function/method overloading. It is when two or more methods can have same name if they differ in parameters.
Golang does not support generics.Java supports generics. Generics means parameterized types. The idea is to allow type (Integer, String, … etc, and user-defined types) to be a parameter to methods, classes, and interfaces. Using Generics, it is possible to create classes that work with different data types.
Golang supports channel. A channel is a medium through which a goroutine communicates with another goroutine and this communication is lock-free.Java does not support channel.
Golang does not contain do-while and while statement.Java contains do-while and while statement.
Go language programs are more compact than Java programs.Java programs are less compact than Go programs.
Threads in Go are cheap.Threads in Java are expensive in comparison to Go.
Go supports public and private functionalities in different way than Java. Although Go doesn’t support private and public keywords, the first letter of the function name decides if it's Public(Upper case) or private(lower case).In Java, methods can be public or private.
