The multiple case labels method provides an elegant solution to this challenge. This section will explore how this method enhances code clarity and efficiency by handling multiple values within aswitchstatement. Imagine a scenario where you want to categorize days of the week based on their position...
Let’s see the syntax for a switch statement with multiple cases. switch (Variable / Expression) { case Case_Value1: case Case_Value2: case Case_Value3: case Case_Value4: // code inside the case // optional break break; case Case_Value5: case Case_Value6: case Case_Value7: case ...
javaSE-第62篇-switch case byte、short、int、char,在jdk7.0及之后还可以是String类型,枚举 在switch中编写任意多个casecase后面常量值得类型必须与表达式的类型一致break; //表示中断,当遇到break则执行switchcase外面的语句default是可有可无的,如果有则一个switch中最大编写一个default,当所有case都不满足时,则执...
当找到一个匹配的case后,程序会执行该case下的语句。 break语句至关重要:执行完一个case块后,如果遇到break语句,则switch语句终止,程序跳到switch结构之后的第一条语句。如果没有break,则会发生“**穿透 (fall-through)**”现象,即...
Theswitchkeyword is followed by an expression in parentheses (this can be a variable or a calculated value). The result of this expression is then compared with the values for eachcasein the structure. If there’s a match, the block of code associated with thatcaseis executed. ...
