Java – Add certificates to key-store and trust-store

certs private key(client) and client side certs all in pem format
I have to add these in trust store and keystore. how can i do so?
till now i have commands in cmd(windows):

1. to generate pkcs (key:client private key, cert:client side cert, ca:cacert): openssl pkcs12 -inkey key.pem -in cert.pem -export -out keystored.p12 -certfile ca.pem

2. keytool -importkeystore -destkeystore mykeystore.jks -srckeystore keystore.p12 -srcstoretype pkcs12

Are these commands correct?

I have written a program which connects the server through ssl. However it shows error
Exception in thread "main" javax.net.ssl.SSLPeerUnverifiedException: peer not authenticated
at sun.security.ssl.SSLSessionImpl.getPeerCertificates(Unknown Source)

program below:
(program is to get docker info)
