有什么方法可以将“ OR”（||）条件分隔为其他条件？

Question

if(resellerContract.getStartDate() == null || 
                DateUtil.getDateInformat(DateUtil.YYY_MM_DD, resellerContract.getStartDate()).before(DateUtil.getDateInformat(DateUtil.YYY_MM_DD,new Date()))){
            validStartDate = false;
            logger.error("SPAC Start date is null");   
            validationErrors.add(new ValidationError(ResellerServiceErrorCode.SPAC_START_DATE_NULL));   
        }

i want to seperate validation for both differnt condtion how i can do that using if else or if if or what should i use because i want to send different error message

Answer 1

Can't you just use a "elseif" statement?

like eg:

if(resellerContract.getStartDate() == null) {
      ....
            validStartDate = false;
            logger.error("SPAC Start date is null");   
            validationErrors.add(new ValidationError(ResellerServiceErrorCode.SPAC_START_DATE_NULL));
 } else if (DateUtil.getDateInformat(DateUtil.YYY_MM_DD, resellerContract.getStartDate()).before(DateUtil.getDateInformat(DateUtil.YYY_MM_DD,new Date()))){
      ....
            validStartDate = false;
            logger.error("SPAC Start date is null");   
            validationErrors.add(new ValidationError(ResellerServiceErrorCode.SPAC_START_DATE_NULL));   
}

Why not just separate the compound if statement into two if statements? Please clarify your intention; I feel that I may be giving you a trivial answer.

if (resellerContract.getStartDate() == null) {
    validStartDate = false;
    logger.error("SPAC Start date is null");   
    validationErrors.add(new ValidationError(ResellerServiceErrorCode.SPAC_START_DATE_NULL));   
}

if (DateUtil.getDateInformat(DateUtil.YYY_MM_DD, resellerContract.getStartDate())
            .before(DateUtil.getDateInformat(DateUtil.YYY_MM_DD,new Date()))) {
    //some other code
}
