在while循环中声明字符串变量而不在整个过程中循环-java
我被困在一个应该声明一个名为“phrase”的字符串变量的地方,在这里它不应该一直循环 给你一个想法,我的任务是:类似于选项1,不同的是用户在输入第一组的结果时输入'N'(而不是'Q')。然后,程序输入第二个团队名称及其结果,直到输入“Q”。输出两条语句,如选项1中的语句,然后是第三条语句,说明哪支球队排名第一(基于分数) 样本输入:在while循环中声明字符串变量而不在整个过程中循环-java,java,loops,while-loop,Java,Loops,While Loop,我被困在一个应该声明一个名为“phrase”的字符串变量的地方,在这里它不应该一直循环 给你一个想法,我的任务是:类似于选项1,不同的是用户在输入第一组的结果时输入'N'(而不是'Q')。然后,程序输入第二个团队名称及其结果,直到输入“Q”。输出两条语句,如选项1中的语句,然后是第三条语句,说明哪支球队排名第一(基于分数) 样本输入: 2 Toronto W W L O W O W N Montreal // how would I make this appear in the same wh

具体说明了什么?那么“W”表示2分,“L”表示0分,“O”表示玩家在“蒙特利尔”场景中得到的1分,应该是“蒙特利尔赢3分”,但我得到的是“蒙特利尔赢11分”,这是为什么?那么一场胜利值2分,一场损失值0分,加时赛值1分。因此,由于蒙特利尔有6次失利,1次获胜,1次失利,总得分将为0+0+0+0+0+0+0+2+1=3分,我用选项2的新代码编辑了我的帖子,我的输出显示了玩家每赢一次应该得到多少分(W
