### Question:
Ed25519EncodedGroupElement { @Override public String toString() { return String.format( "x=%s\ny=%s%n", this.getAffineX().toString(), this.getAffineY().toString()); } Ed25519EncodedGroupElement(final byte[] values); byte[] getRaw(); Ed25519GroupElement decode(); Ed25519FieldElement getAffineX(); Ed25519FieldElement getAffineY(); @Override int hashCode(); @Override boolean equals(final Object obj); @Override String toString();  }### Answer:
@Test public void toStringReturnsCorrectRepresentation() { final Ed25519EncodedGroupElement encoded = Ed25519GroupElement.p2(Ed25519Field.ZERO, Ed25519Field.ONE, Ed25519Field.ONE).encode(); final String encodedAsString = encoded.toString(); final String expectedString = String.format( "x=%s\ny=%s%n", "0000000000000000000000000000000000000000000000000000000000000000", "0100000000000000000000000000000000000000000000000000000000000000"); MatcherAssert.assertThat(encodedAsString, IsEqual.equalTo(expectedString)); }
