Fix bug in JavaRegressionMetricsExample.
the original code cant visit the last element of the"parts" array.
so the v[v.length–1] always equals 0
## What changes were proposed in this pull request?
change the recycle range from (1 to parts.length-1) to (1 to parts.length)

debug it in eclipse (´〜｀*) zzz.
