In such case, break is used. It terminates the nearest enclosing loop when encountered (without checking the test expression). This is similar to how break statement works in Java. How break works? It is almost always used with if..else construct. For example, for (...) { if (testExpr...
We have truncated the output, but the execution goes on and on. 2. Infinite While loop with break statement In the following program, we have an infinite while loop to print from numbers from 1 to infinity. Also, we have abreakstatement that runs when the value ofiis 5. Main.kt </>...
can be used as an expression or a statement (i.e., it can return a value or not) has a better and safer design can have arbitrary condition expressions can be used without an argument Let’s see an example of all of these features. A Safe and Powerful Design First of all, when has...
In the above example, you can replace fun getName(firstName: String, lastName: String): String = "$firstName $lastName" with fun getName(firstName: String, lastName: String) = "$firstName $lastName" This is just the brief introduction to functions in Kotlin. Recommended articles ...
package geometry.example import geometry.shapes.createRandomRectangle //通过名字导入函数 fun main(args: Array<String>) { println(createRandomRectangle().isSquare)//非常不可能打印"true" } 1. 2. 3. 4. 5. 6. 7. 通过包名后面加上.*,你可以导入特定包里面定义的所有声明。注意,星号导入(star import...
Lets say if we don’t handle the exception in the above example then the program would terminate abruptly. Here we didn’t handle exception so the program terminated with an error. fun main(args:Array<String>){varnum=10/0println("BeginnersBook.com")println(num)} ...
Sometimes you want to break out of a loop early. You can do this using thebreakstatement, which immediately stops the execution of the loop and continues on to the code after the loop. For example, consider the following code: sum =1while(true) { sum = sum + (sum +1)if(sum >=100...
1-Break和Continue标签 2-在标签处的Return 3-实例讲解 1-Returns and Jumps 1-Break and Continue Labels 2-Return at Labels 1-返回和跳转 Kotlin有三种结构跳转表达式: return. 默认从最近的封闭方法(包含该return的方法)或者匿名方法返回。 break. 终止最近的封闭循环。
We use when statements and expressions. We are using the when statement with the else statement, or we can also use the when statement without the else statement. Conclusion The switch cases we are using in java or other languages, in that we have not required break statement at the ending...
在纯Kotlin 项目中,推荐的目录结构遵循省略了公共根包的包结构(例如,如果项目中的所有代码都位于“org.example.kotlin”包及其子包中,那么“org.example.kotlin”包的文件应该直接放在源代码根目录下,而 “org.example.kotlin.foo.bar”中的文件应该放在源代码根目录下的“foo/bar”子目录中)。
