1. for 循环 for 循环通常用于已知循环次数的情况。 java public class ForLoopExample { public static void main(String[] args) { for (int i = 0; i < 5; i++) { System.out.println("i = " + i); } } } 2. while 循环 while 循环用于在条件为真时重复执行代码块。 java public class ...
4. Difference betweenWhile-loop andFor-loop Unlike thefor-loopstatement, the condition-expression inwhileloop statement is not optional.In general, afor-loopstatement can be converted to awhile-loopstatement. However, not allfor-loopstatements can be converted to awhile-loopstatement. The following...
The while loop loops through a block of code as long as a specified condition is true:SyntaxGet your own Java Server while (condition) { // code block to be executed } In the example below, the code in the loop will run, over and over again, as long as a variable (i) is less ...
So back to the loop itself. We start off with the "for" keyword. Notice how it is in lower case. Next the terms of the loop go inside the parenthesis. We'll take this one step at a time. The first thing you see is int x = 0; This is the starting point of the loop. It sa...

Override the superclass method addAndAverage() to sum from 222 to 6699, and compute theaverage. Hint: Declare an int variablecalled count to count the numbers in thespecified range. Use a for loop.Add a class named TestRun with a main() method.Note that this is not a subclass of the...
Java: for(;;) vs. while(true) What is the difference between a standardwhile(true)loop andfor(;;)? Is there any, or will both be mapped to the same bytecode after compiling? Semantically, they'recompletely equivalent. It's a matter of taste, but I thinkwhile(true)looks cleaner, ...

但是我们一般是需要else结尾的,而且我们可以用in来表达 当然,你还可以用is来判断类型,这里就不讲了 3.For 循环 4.While 循环 四.Break和continue Kotlin 有三种结构化跳转表达式: return。默认从最直接包围它的函数或者匿名函数返回。 break。终止最直接包围它的循环。
