Java 这个数组是否可以检查用户输入的字母？
这是否可以作为一个数组来检查程序用户输入的字母Java 这个数组是否可以检查用户输入的字母？,java,variable-assignment,Java,Variable Assignment,这是否可以作为一个数组来检查程序用户输入的字母 final int LOW = 'A'; //smallest possible value final int HIGH = 'Z'; //highest possible value int[] letterCounts = new int[HIGH - LOW + 1]; String guessletter; char[] guessletter; int offset; //array index // set constan

正如@Bernard所指出的，您粘贴的代码除了要求用户提供一个字母外，什么都不做。如果您的问题是关于跟踪用户猜测的字母是否正确（这样程序就不会接受已经猜测的字母），那么是的，您可以通过增加与用户猜测的字母对应的数组元素来使用
