Solidity is used for Smart Contracts and crypto tokens. Which is an alternative to SOLIDITY..???

Solidity is a language to interact with a blockchain. To build your own blockchain you can use anything, but ideally you'll want a compiled language. If you don't need your own blockchain and wanted to create a cryptocurrency on the Ethereum blockchain, you could use solidity to do that. Solidity can also be used on other private blockchains, though.
