I encountered a problem that different derived paths get different addresses

[macrotea]

Hello, I am very happy to use your powerful encryption library, but when I was testing the demo example on this page (https://iancoleman.io/bip39/#english), I encountered a problem: From Derived Addresses Title，
In the Table tab , how to generate different addresses, public keys, and private keys according to different Derived Paths. When I use the BIP39 library, I don’t know how to implement it. cloud you give me a java demo? Because the page is implemented through the javascript lib, but how to implement the java BIP39 library, I read all the unit tests and don’t know how to write the code, so I need your help. thanks！
