Java代码优化：使用switch语句获取工资周期

int symbolicPeriodId = ...; // assuming symbolicPeriodId is an integer\n\nswitch (symbolicPeriodId) {\n case 0:\n kDateSpan = employeePayPeriod.getPreviousPayPeriod();\n break;\n case 1:\n kDateSpan = employeePayPeriod.getCurrentPayPeriod();\n break;\n case 2:\n kDateSpan = employeePayPeriod.getNextPayPeriod();\n break;\n default:\n // handle invalid symbolicPeriodId here\n break;\n}
