Programmers makes mistake. If theconditional-expressiongiven in while loop never terminatesthen the loop will result in an infinitewhile-loop. For example, in the previous program, if theindexvalue is not incremented after each iteration, then the condition will never terminate. In the next example...
If you are familiar withwhile and do...while loops in Java, you are already familiar with these loops in Kotlin as well. Kotlin while Loop The syntax ofwhileloop is: while (testExpression) { // codes inside body of while loop } How while loop works? The test expression inside the par...

If the test expression in the while and do...while loop never evaluates to false, the body of loop will run forever. Such loops are called infinite loop. For example: Infinite while loop while (true) { // body of while loop } Infinite do...while loop do { // body of while loop...

at cwk/cwk.test1.main(test1.java:31) 我实际上只是一个大学的学生,在一个模块上寻求一些帮助。我不是程序员,我不是在上编程课程。请不要删除我的问题。 nextLine时,它将读取整行,直到遇到\n或文件的结尾。当您调用nextInt和nextDouble时,它将跳过前面的任何空白,但是它不会在后面使用任何空白。
