Implementation of solid transfer function (based on transfer)

contract cs{
    
    
    address public creator;
    
    constructor()public payable{
    
        creator = msg.sender;
    }
    
    function getETH()public{
    
	    require(
	            address(this).balance>=0.01 ether,
	            " The contract is out of money , Pay for the contract "
	            );
        address _owner = msg.sender;
        _owner.transfer(0.01 ether);
    }
    
    function()payable{
    
        
    }
    
}

Note:
When using this contract, you need ether in the contract
Otherwise, the contract will not be able to send ether to the caller
You can send a certain amount of ether to the contract to test when creating the contract
