The 1.break statement is used to jump out of a loop. After the break statement jumps out of the loop, the code after the loop continues to execute, if any. The Continue is used to skip an iteration in the loop. 2 . Label:statements is used to jump directly to the line specified by the identifier and start execution, which can only be used by break and continue. The 3.try statement tests the code block for errors. The catch statement handles the error. The throw statement creates a custom error

structs, we can package all relevant information that describes the same employee, including name, gender, age, and salary, into a single struct type, and then use this struct type to define an array of employee data, which is not only simple in code, And the above impossible task can also be done easily://Package variables that describe the multiple attributes of the "employee" complex as a structstructemployee{String M_strname;//NameBOOL M_bmale;//Genderint m_nage;//Ageint m_nsalary;//Wages};

This article describes the basic use and simple concepts of interfaces in Java. Interfaces are a bit like abstract classes, interfaces are not classes, interfaces simply declare methods, and there is no specific implementation. In the Java programming language is an abstract type, which is a collection of abstract methods, and interfaces are usually declared with interface. A class inherits the abstract method of an interface by inheriting the interface. The interface cannot be instantiated, but

Lambda is just an expression, and the function body is much simpler than def. The body of a lambda is an expression, not a block of
