Hi,

You can find a step by step tutorial for a similar hello world example here:
http://www.sparsity-technologies.com/StartingGuide/Index.html

The FindObject method can be used to find the nodes if the strings "hello" and "world" are unique ids:
http://www.sparsity-technologies.com/downloads/javadoc-java/html/com/sparsity/sparksee/gdb/Graph.html#findObject(int,%20com.sparsity.sparksee.gdb.Value)

Or you could use Select to find the nodes if you may want to find several nodes with the "hello" or "world" value when the string is not unique.
http://www.sparsity-technologies.com/downloads/javadoc-java/html/com/sparsity/sparksee/gdb/Graph.html#select(int,%20com.sparsity.sparksee.gdb.Condition,%20com.sparsity.sparksee.gdb.Value)

Once you have the two specific nodes that you wanted, you can use FindEdge to get a single edge of a specific type that connects the two nodes (if it exists) when you know that there is only one edge (or you only want one of the possibly several edges of this type connecting this two nodes).
http://www.sparsity-technologies.com/downloads/javadoc-java/html/com/sparsity/sparksee/gdb/Graph.html#findEdge(int,%20long,%20long)

You can also use Edges to get all the edges of a specific type connecting the two nodes.

Best regards.
