Java 分割符的使用

  @Override
    public int deleteByArrayListAndProgramId(String arrayList, String programId) {
    
    
        if(PublicUtil.isEmpty(arrayList) || PublicUtil.isEmpty(programId))
            return 0;
       String[] strArr = arrayList.split(",");
       int count = 0;
       for(String arrId : strArr ) {
    
    
           TArrayOfPro tArrayOfProDelete = new TArrayOfPro();
           tArrayOfProDelete.setProgramid(programId);
           tArrayOfProDelete.setArrayid(arrId);
           tArrayOfProMapper.delete(tArrayOfProDelete);
           count++;
       }
       return count;
    }
