EBCDIC (Extended Binary Coded Decimal Interchange Code) is a legacy character encoding from IBM mainframes that needs conversion to ASCII for modern systems. Java provides native support for this conversion through the Charset API. The basic approach involves decoding EBCDIC bytes using the appropriate code page (like Cp037), converting to a Java String (Unicode internally), then re-encoding to ASCII or UTF-8. For small data, direct String conversion works well. For large files, streaming approaches using InputStreamReader and OutputStreamWriter are more memory-efficient. The key is identifying the correct EBCDIC variant and using Java's built-in charset support to handle the transformation reliably.
