The expression can be a byte, short, char, and int primitive data types.
#USE SWITCH CASE JAVA CODE#
It is a multi-way branch statement that provides paths to execute different parts of the code based on the value of the expression.
I thought because there are no brackets for the for statement that it would only loop for the if statement but eclipse says otherwise(else if also loops from 0 to the length of the array). Using a switch case in java optimizes the readability of the code while working on multiple test expressions. The switch case is very commonly used in Java. If there is a match, the associated block of. The problem is that when i highlight the other break(in eclipse), it says that the breaks are attached to the for statement as well, but i only wanted the for statement to be attached to the if statement, not the else if statements as well. The value of the expression is compared with the values of each case. The default case can be used for performing a task when none of the cases is true. In this case if it does, we declare the value variable to be equal to 2, and we break out of the loop. A switch statement can have an optional default case as well at the last to give the default condition to be executed. Let's say value is currently 1, we go to case 1 and our for loop goes through the array to see if each element matches with the whatever_value variable.
The execution of code stops on encountering this keyword, and the case testing inside the block ends as the match is found. Break keyword: As java reaches a break keyword, the control breaks out of the switch block. For the purpose of my question I've only included case 1, but the other cases are the same. The switch case in java is used to select one of many code blocks for execution.
