Will continue from your code itself . This program block will provide all the noun phrases in sentence. Use getTagNodes() method to get Tokens and its types

Parse topParses[] = ParserTool.parseLine(line, parser, 1);
Parse words[]=null; //an array to store the tokens
//Loop thorugh to get the tag nodes
for (Parse nodes : topParses){
        words=nodes.getTagNodes(); // we will get a list of nodes
}

for(Parse word:words){
//Change the types according to your desired types
    if(word.getType().equals("NN") || word.getType().equals("NNP") || word.getType().equals("NNS")){
            System.out.println(word);
            }
        }
