Perhaps you should try some spelling variations:
"testing computation using java programming" » "testing imputation using java programming" (Expand search), "testing population using java programming" (Expand search), "testing mutation using java programming" (Expand search), "testing computations using java programming" (Expand search), "testing computation in java programming" (Expand search), "testing composition using java programming" (Expand search), "testing computation using and programming" (Expand search), "testing computation using based programming" (Expand search), "testing computation using goal programming" (Expand search)
"using in python python programming" » "using in pythons python programming" (Expand search), "using in piton python programming" (Expand search), "using in pitons python programming" (Expand search), "using _ python python programming" (Expand search)

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"testing computation using java programming\") OR (\"using in python python programming\"))~".
• Removing quotes may allow a broader search: (( testing computation using java programming ) OR ( using in python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("testing computation using java programming") OR ("using in python python programming"))*.
