### Question:
Dimension implements Comparable<Dimension> { public String getShortName() { return this.shortName; } Dimension(String name, int length);  Dimension(String name, int length, boolean isShared, boolean isUnlimited, boolean isVariableLength); private  Dimension(Builder builder); int getLength(); String getShortName(); boolean isUnlimited(); boolean isVariableLength(); boolean isShared(); String makeFullName(Variable v); String makeFullName(Group containingGroup); @Override boolean equals(Object o); @Override int hashCode(); int compareTo(Dimension odim); @Override String toString(); Builder toBuilder(); static Builder builder(); static Builder builder(String name, int length); static final Dimension VLEN; }### Answer:
@Test public void testAnonDimFullName() throws Exception { Dimension dim = new Dimension(null, 5, false, false, false); assertThat(dim.getShortName()).isNull(); }
