In this example, the condition to continue the loop is always true, but it will be successfully stopped when the variable i becomes 0 through the use of break inside the conditional statement. It provides an easy way to dispatch execution to different parts of code based on the value of the expression. The switch statement is a multiway branch statement. It is like an if-else-if ladder statement. For example: Valid expressions for switch: switch(1+2+23) switch(12+34) Invalid switch expressions: switch(ab+cd) switch(a+b+c) 4) Nesting of switch statements are allowed, which means you can have switch statements inside another switch. Example: Consider the following java program, it declares an int named day whose value represents a day(1-7). 3) The expression given inside switch should result in a constant value otherwise it would not be valid. In simple words, the Java switch statement executes one statement from multiple conditions. Note: Java switch statement is a fall through statement that means it executes all statements if break keyword is not used, so it is highly essential to use break keyword inside each case. Switch case statements are a substitute for long if statements that compare a variable to several integral values. The switch statement is a multi-way branch statement. The following example demonstrates a loop that includes one break. How a statement is handled inside switch block but outside case.
