Switch statement can be replaced with enhanced 'switch' Switch语句可以替换为增强的“Switch” //原版语法 switch(choiceSecond){ case "1": this.delete(); break; case "2": this.buy(); break; case "3": empJudge = true; break; default: System.out.println("非法输入，请重新键入命令"); } //语法糖 switch (choiceSecond) { case "1" -> this.delete(); case "2" -> this.buy(); case "3" -> empJudge = true; default -> System.out.println("非法输入，请重新键入命令"); }
