Java. Lang. illegalargumentexception: cannot format given object as a number error occurs when inserting data into jtable.

When adding data to jtable

Java. Lang. illegalargumentexception: cannot format given object as a number

Error.

1) Check the Add process. Convert all data types to strings and then add them. In the program, use float. tostring () to convert float to string.

2) Check the Data Type of the jtable column, which can be string or float.

Cause: the data type to be added does not match the data type defined in the jtable column.

Solution: 1) do not convert float to string, directly add;

2) convert float to string, change the data type of jtable columns to string, and then add.
