### Question:
ConfigKeyGroup { @Override public boolean equals(Object o) { if (!(o instanceof ConfigKeyGroup)) { return false; } ConfigKeyGroup other = (ConfigKeyGroup) o; return Objects.equals(name, other.name); }  static ConfigKeyGroupBuilder builder(String name); @Override boolean equals(Object o); @Override int hashCode(); static final Comparator<ConfigKeyGroup> ORDERING; static final ConfigKeyGroup DEFAULT; }### Answer:
@Test public void testEquals() { ConfigKeyGroup grp1 = ConfigKeyGroup.builder("group1") .description("test group 1") .build(); ConfigKeyGroup anotherGrp1 = ConfigKeyGroup.builder("group1") .description("test another group 1") .build(); assertEquals(grp1, anotherGrp1); }
