### Question:
StructureBuilder { public abstract StructureBuilder addChar(String name, int length);  static StructureBuilder getBuilder(); static StructureBuilder getBuilder(final Structure existingStructure); abstract Structure build(); abstract StructureBuilder addChar(String name, int length); abstract StructureBuilder addDQ8(String name); abstract StructureBuilder addDynamicList(String name, Structure structure); abstract StructureBuilder addF8(String name); abstract StructureBuilder addI2(String name); abstract StructureBuilder addI4(String name); abstract StructureBuilder addList(String name, Structure structure, int size); abstract StructureBuilder addRecord(String name, Structure structure); abstract StructureBuilder addStatusData(); abstract StructureBuilder addVC(String name);  }### Answer:
@Test public void testAddChar() { final String fieldName = "CHAR_FIELD"; final int dataLength = Integer.MAX_VALUE; builder.addChar(fieldName, dataLength); final Structure structure = builder.build(); validateCharacterField(structure, fieldName, dataLength); }
