public static boolean equal(Object a, Object b)

Determines whether two possibly-null objects are equal. Returns:

true if a and b are both null.

false in all other situations.

This assumes that any non-null objects passed to this function conform to the equals() contract.

public static Objects.ToStringHelper toStringHelper(Object self)

Creates an instance of ToStringHelper.

This is helpful for implementing Object#toString(). Specification by example:

// Returns "ClassName{}" Objects.toStringHelper(this) .toString();

// Returns "ClassName{x=1}" Objects.toStringHelper(this) .add("x", 1) .toString();

// Returns "MyObject{x=1}" Objects.toStringHelper("MyObject") .add("x", 1) .toString();

// Returns "ClassName{x=1, y=foo}" Objects.toStringHelper(this) .add("x", 1) .add("y", "foo") .toString();

// Returns "ClassName{x=1}" Objects.toStringHelper(this) .omitNullValues() .add("x", 1) .add("y", null) .toString();
