数组常数只能在初始化错误中使用

这意味着您必须像这样初始化它：

public class Proj3{    public static String [][] Item = {   {"BH," , "Backhoe," , "200.00"},   {"ER," , "Electric Rake," , "10.00"},   {"EL," , "Electric Lawnmower," , "15.00"},   {"TR," , "Trencher" , "35.00"},   {"MU," , "Mulcher," , "20.00"},   {"TS," , "Tree Sprayer," , "22.00"},   {"CP," , "Cider Press," , "30.00"},   {"PR," , "Pruner," , "12.00"},   {"GE," , "Gas Edger," , "20.00"},   {"RO," , "Roller," , "8.00"}         };public static void main(String [] args){     ...}

如果要使用数组初始化器，则不能拆分声明和赋值。
