Type Casting: Converting a value from one data type to another is called Type Casting Widening or Automatic Type or Implicit Conversion: Converting a lower data type into higher one is called widening type casting Two data types are converted automatically Two data types are compatible Assigning value of a smaller data type to bigger data type byte -- short -- int -- long -- float -- double Narrowing or Explicit Conversion: Assigning a value of larger data type to a smaller data type is called explicit type casting Used for incompatible data types double -- float -- long -- int -- short -- byte Control Flows: A program’s control flow is the order in which the program’s code is executed Code execution flow can be changed by including control flow statements and conditions Conditions determine how many times a line of code gets executed Java provides 3 types of control flow statements: Decision making statements - If, if else, else if Loop statements - while, do while, for Jump statements - break, continue If Else Statement: An if statement is a control flow which performs some action when condition is true An else statement only runs when the condition is false While Loop: Loop executes a block of code repeatedly based on the condition While Loop: It is a control flow statement that allows code to be executed as long as a given condition is true Do While Loop: It is similar to while loop but checks the condition after the statements are executed All statements are executed until the condition is false and loop terminates It will execute the statement at least once For Loop: For statement provides a compact way to iterate over a range of values. It repeatedly loops until a particular condition is satisfied. For Each Loop: Enhanced for loop can be used to iterate through the elements of a collection or an array Break & Continue Statements: Break statement is used to terminate the loop and return the control to first statement after the loop. Continue statement is used to skip the current iteration of the loop and jump to the next iteration of the loop. It can be used with any type of loop like for, while and do while loop. Methods: Method is a block of code which performs a specific task Methods help developers organize their code Methods help us to define a task and reuse it throughout our code Built In Methods: Java has already defined many methods in its library These methods are called built in methods Built in methods can be used by just calling them System.out.println() is a built in method Use dot operator to get access to many built in method To enquire more about Selenium Java Trainings, please contact us at [email protected]
