Fix bug in JavaRegressionMetricsExample. the original code cant visit the last element of the"parts" array. so the v[v.lengthâ1] 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) ## How was this patch tested? debug it in eclipse (´ãï½*) zzz.
