Java 在哪里添加main方法以便正确运行此程序？
我不知道在哪里添加main方法以便运行这个类。帮助我也不确定主方法放在哪里 这个班经营一家美发沙龙。全局变量用于跟踪dailyRevues（总收入美元）、dailyTax（总税额）以及理发次数、永久性和染色次数。此外，还应记录已接受服务的客户数量，并打印一份每日报告，该报告给出了客户总数、理发总数、永久性和染色情况。此外，总收入（收入）和税收需要在每日报告中打印。最后，每个客户花费的平均金额应计算并打印在报告中。如果商店收入达到650美元或以上，那么商店经理将获得每日总收入的5%作为奖金。你应该在报告中包括店长奖金，并从总收入中减去该奖金，得出当天的净收入。如有必要，可以随意添加其他变量和方法 这是我的密码Java 在哪里添加main方法以便正确运行此程序？,java,methods,main-method,Java,Methods,Main Method,我不知道在哪里添加main方法以便运行这个类。帮助我也不确定主方法放在哪里 这个班经营一家美发沙龙。全局变量用于跟踪dailyRevues（总收入美元）、dailyTax（总税额）以及理发次数、永久性和染色次数。此外，还应记录已接受服务的客户数量，并打印一份每日报告，该报告给出了客户总数、理发总数、永久性和染色情况。此外，总收入（收入）和税收需要在每日报告中打印。最后，每个客户花费的平均金额应计算并打印在报告中。如果商店收入达到650美元或以上，那么商店经理将获得每日总收入的5%作为奖金。你应该
