1/*2三种循环的区别。341. 如果条件判断从来没有满足过,那么for循环和while循环将会执行0次,但是do-while循环会执行至少一次。52. for循环的变量在小括号当中定义,只有循环内部才可以使用。while循环和do-while循环初始化语句本来就在外面,所以出来循环之后还可以继续使用。6*/7publicclassDemo13LoopDifference {8pu...

aThe difference between do-while and while is that do-while evaluates its expression at the bottom of the loop instead of the top. Therefore, the statements within the do block are always executed at least once, as shown in the following DoWhileDemo program: 之间区别,做当,并且,当是时,做...

By hard coding the Boolean expression totrue, we've created an infinite loop--a loop that will never end, at least, not as it's currently written. We would need a way to break out of the loop inside of the code block. We'll discuss the exit criteria of ado-whilein a bit. ...
The Java programming language also provides a do-while statement, which can be expressed as follows: do { statement(s) } while (expression); The difference between do-while and while is that do-while evaluates its expression at the bottom of the loop instead of the top. Therefore, the ...
