Am using io.kubernetes to create dynamic kubernate pods from java.

I wanted to set the resources using KubernetesConstants class as shown in bellow

Jave Code:

        Map<String, Quantity> requests = new HashMap<>();
        requests.put("memorey", Quantity.fromString(Long.toString(128)));
        requests.put("cpu", Quantity.fromString(Long.toString(1)));
        V1ResourceRequirements resourceRequirements =new V1ResourceRequirements();
        resourceRequirements.setRequests(requests);
        Map<String, Quantity> limits = new HashMap<>();
        limits.put("memory", Quantity.fromString(Long.toString(512)));
        limits.put("cpu", Quantity.fromString(Long.toString(1)));
        resourceRequirements.setLimits(limits);
        container.setResources(resourceRequirements);   

Can someone help me how set CPU resources as 300m as shown bellow in yaml file

yaml file :

resources:
  limits:
    cpu: "1"
  requests:
    cpu: 500m
