顺便说一下,你的switch语句是错误的。 - Anonymous 0 如果你真的想使用 switch 语句,你可以将 mark 除以 10 并让 case 10 和 case 9 等于 A,然后你可以在 case 8 到 case 5 中放置 if 条件语句,default 情况下为 f。 - kimo 0 不幸的是,Java没有像Javascript一样的switch-ranges,因此获得所需...
4.switchArgument andcaseValues Now let’s discuss the allowed types ofswitchargument andcasevalues, the requirements for them and how theswitchstatement works with Strings. 4.1. Data Types We can’t compare all the types of objects and primitives in theswitchstatement.Aswitchworks only with four ...
class Main { public static void main(String[] args) { int expression = 2; // switch statement to check size switch (expression) { case 1: System.out.println("Case 1"); // matching case case 2: System.out.println("Case 2"); case 3: System.out.println("Case 3"); default: Syste...
How Does Case Statement work in Java? As described above, Case in a particular Switch statement is executed when the value of the expression matches with the Case value. If none of the value matches case values, then the default statement defined in the Switch block is executed; otherwise, ...
Traditional Switch Statement publicclassSwitchStatement{publicstaticvoidmain(String[]args){System.out.println("Monday is : "+isWeekDay(Day.TUE));System.out.println("Monday is : "+isWeekDay(Day.SUN));}publicstaticBooleanisWeekDay(Dayday){Booleanresult=false;switch(day){caseMON:result=true;break...
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...
intday=3;switch(day){case1:System.out.println('Monday');break;case2:System.out.println('Tuesday');break;// ...}#Output:#'Tuesday' Java Copy In this example, we have a switch statement that checks the value of the variableday. Depending on the value, it executes a different code blo...
Switch case statement is used when we have number of options (or choices) and we may need to perform a different task for each choice. The syntax of Switch case statement looks like this – switch (variable or an integer expression) { case constant: //Ja
