kandi X-RAY | jhdf Summary

jhdf is a Java library typically used in Institutions, Learning, Education applications. jhdf has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. However jhdf build file is not available. You can download it from GitHub, Maven.

This project is a pure Java implementation for accessing HDF5 files. It is written from the file format specification and is not using any HDF Group code, it is not a wrapper around the C libraries. The file format specification is available from the HDF Group here. More information on the format is available on Wikipedia. The intention is to make a clean Java API to access HDF5 data. Currently, the project is targeting HDF5 read-only compatibility. For progress see the change log. Java 8, 11 and 17 are officially supported. Here is an example of reading a dataset with jHDF (see ReadDataset.java). For an example of traversing the tree inside a HDF5 file see PrintTree.java. For accessing attributes see ReadAttribute.java.

How to split string of mulitdimensional array

You get the StringIndexOutOfBoundsException because you have some empty strings in your arrOfStr1 array. The n.charAt(0) expression is causing the exception because there is no characters in some of the strings. Use the debugger to see whats really in the data array before you try to remove the single commas.

Anyways, here is the fix, modify one line in your code:
