在Java中,当你尝试使用除法运算符('/')对BigDecimal对象和int值进行运算时,会出现编译错误,提示“operator '/' cannot be applied to 'java.math.BigDecimal', 'int'”。这是因为BigDecimal类并不支持直接与基本数据类型(如int)进行算术运算。为了解决这个问题,你可以采用以下两种解决方案:
Operator '!=' cannot be applied to 'int', 'null' 运算符“!=”不能应用于“int”,“null” lqw.eq(bo.getClassId() !=null, StudentClass::getClassId, bo.getClassId()); 把实体类中int型数据改成Long型 privateLong classId;
Operator '&' cannot be applied to 'int', 'boolean' 在运行以下代码时,系统报错 Operator '&' cannot be applied to 'int', 'boolean' 原因:J在ava语法中关系运算符的优先级大于逻辑运算符,所以先算(a-1) != 0得到一个boolean类型的值。&左右是布尔类型时会转换成逻辑运算符进行逻辑运算,否则会进行位...

Operator ‘==‘ cannot be applied to ‘int‘, ‘null‘ 今天写代码的时候遇到了一个bug: 如何解决: if(quicklink.getId() ==null) 修改好 Integer id = quicklink.getId();if(id==null || id == 0){} 就好了
The error "Operator '+' cannot be applied to types 'Number' and 'number'" occurs when we use the `Number` type instead of `number` (lowercase `n`).
1. 2. 3. 4. 5. 6. 7. 8. 9. 程序报错:Operator ‘<=’ cannot be applied to ‘boolean’,‘int’ 原因是Java中 if 语句不支持这样的表达方式。正确的表达方式应该为 if( 3<= i && i <= 5 ){ System.out.println("春天"); }else if( 6 <= i && i <= 8 ){ ...

Float price1 = Float.valueOf(price);Float num1 = Float.valueOf(num);你这两句得到的price1,num1是Float(包裹类类型,是一个类),而不是float类型(可以数值计算的浮点型)。应该该成 float price1=Float.parseFloat(price);float num1=Float.parseFloat(num);xiaoji=num1*price1;float...
