java.lang.String和java.lang.Integer是Java中的两种完全不同的数据类型。String是一个对象,用于表示文本数据,而Integer是一个包装类,用于表示整数值。由于它们之间没有继承关系,因此它们之间不兼容,不能直接进行类型转换。 3. 提供解决inconvertible types; cannot cast 'java.lang.string' to 'java.lang.integer'错...
inconvertible types; cannot cast 'android.app.Fragment' to 'com.example.sevenun.littledemo.fragment.NewsTitleFragment' 出现上面的错误,是因为我们在有的类导入了android.supoort.v4.app.Fragment,而在有些类导入了android.app.Fragment。 事实上,这两个不能相互转换,所以我们应该统一,要么都导入android.app.Fr...

会报错:inconvertible types: STRING -> DOUBLE [from=, to=perratio] 因为PERRATIO为:double类型 用Updateable自动转换出来'0.001' 要改成0.001为才正确,如: UPDATE "users" SET "CREATETIME"='2025-01-15 21:50:44.713', "MODIFYID"=12, "MODIFYBY"='blogadmin', "MODIFYTIME"='2025-01-16 10:00:0...

对象引用类型转换，指的是子类强制转换为父类的转换。之所以需要强制转换，是因为子类包含比父类更多的属性和方法，强制转换后，子类以父类的形态出现，暂时只能使用父类的方法。如果使用非父子类强制转换，那么就会提示语法错误: inconvertible types; cannot cast 'java.lang.Double' to 'java.lang.Integer'。
In that case, the classpath sources should have the old jikes stuff stripped out. There are still references to jikes that lead userslike myself to think that jikes is still supported. For instance, the configure script still accepts the --with-jikes option. ...
