Example of loan amount calculation function implemented in Java

This article describes the loan amount calculation function implemented in Java. Share with you for your reference, as follows:

Problem and code:

Operation results:

Summary of knowledge points:

Cast of data type (explicit conversion), math.pow, priority

experience:

I feel that the priority of Java is similar to that of others. Java is particularly strict with types, and will not automatically convert all of them. A small type can be widened by becoming a large type, and a large type can be widened by becoming a small type. If a type is not converted, an error will occur.

In addition, when the variable types are different, there will be an error if it is not converted. For example, assign int to short or byte

I didn't feel much trouble at first, but now it does seem a little trouble.. And I don't quite understand the meaning of object-oriented. Ow~~

Finally, record a knowledge point: in the output statement of Java, some "line feed, carriage return, tab, etc. cannot be used, but escape characters can be used, such as:

Double quotation mark @ h_ 419_ 35 @ is \ "single quote @ h_419_35 @ is \ 'backspace @ h_419_35 @ is \ B tab@H_419_35 @Yes \ tfound @ h_ 419_ 35 @ \ nreturn @ h_ 419_ 35 @ \ r backslash @ h_ 419_ 35@ \\
