Question

Which Java type does wca4z typically use when generating code for COBOL numeric fields defined with PIC 9(11)V9(2) COMP-3?

Accepted Answer

int, because COMP-3 fields are always integers in COBOL — Think of it like working hands-on with IBM mainframe systems — the answer here is 'int, because COMP-3 fields are always integers in COBOL'. BigDecimal is the Java type that matches COBOL packed decimal (COMP-3) arithmetic because it provides exact decimal representation and configurable rounding behavior, preserving financial calculation . On real mainframe exams, this concept comes up repeatedly so make sure you have it locked in.

Answer

float, because packed decimal values are approximated using IEEE 754 single precision

Answer

BigDecimal, to preserve exact decimal arithmetic and precision matching COBOL packed decimal behavior

Answer

long, because COBOL packed decimal values are stored as 64-bit binary integers internally
