Perhaps you should try some spelling variations:
"and computational java computer program" » "and computacional java computer program" (Expand search), "and computational data computer program" (Expand search), "and computational and computer program" (Expand search), "_ computational java computer program" (Expand search)
"by computation using computing program" » "by computations using computing program" (Expand search), "by computation in computing program" (Expand search), "by composition using computing program" (Expand search), "by computation using consulting program" (Expand search), "by computation using computador program" (Expand search), "by computation using computer programs" (Expand search), "by computation using competing program" (Expand search), "by computation mining computing program" (Expand search), "by computation using conducting program" (Expand search), "by computational using computing program" (Expand search), "of computation using computing program" (Expand search), "_ computation using computing program" (Expand search)

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("and computational java computer program") OR ("by computation using computing program"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"and computational java computer program\") OR (\"by computation using computing program\"))".
• Removing quotes may allow a broader search: (( and computational java computer program ) OR ( by computation using computing program )).
• Adding a wildcard symbol may retrieve word variants: (("and computational java computer program") OR ("by computation using computing program"))*.
