The switch statement falls under decision-making statements, allowing your program to choose different paths of execution based on an expression’s outcome. Grasping the Concept of ‘Fall Through’ in Switch Statements A unique characteristic of the switch statement in Java is the ‘fall through’ ...
Compile and run the above program using various command line arguments. This will produce the following result −Well done Your grade is 3 Example 3In this example, we're showing use of switch statement where cases are based on a String. We've created a variable grade. Based on value ...
We initialize anintvariable nameddaywith a value of4. The subsequentswitchstatement evaluates the value ofday. The firstcaseline uses arrow syntax to group values1,2,3,4, and5together. This eliminates the need for redundant code blocks, and the arrow (->) succinctly associates this group of...
