You can make a boolean equivalent for each checks for age, name, status, and location as a workaround.

    boolean isAgeBlank = StringUtils.isBlank(age);
    boolean isNameBlank = StringUtils.isBlank(name);
    boolean isStatusBlank = StringUtils.isBlank(status);
    boolean isLocationBlank = StringUtils.isBlank(location);
    if(isAgeBlank || isNameBlank || isStatusBlank || isLocationBlank){
        //do whatever you want in each case
        if(!isAgeBlank) System.out.println("Age provided!"); //do the rest
        return true;
    }else{
        return false;
    }
