Method Detail

equals

public static boolean equals(boolean aObj1,
             boolean aObj2)

Check if two values are equal. This method only exists, so that no type differentiation is needed.

Parameters:

aObj1 - First value

aObj2 - Second value

Returns:

true if they are equal, false otherwise.

equals

public static boolean equals(byte aObj1,
             byte aObj2)

Check if two values are equal. This method only exists, so that no type differentiation is needed.

Parameters:

aObj1 - First value

aObj2 - Second value

Returns:

true if they are equal, false otherwise.

equals

public static boolean equals(char aObj1,
             char aObj2)

Check if two values are equal. This method only exists, so that no type differentiation is needed.

Parameters:

aObj1 - First value

aObj2 - Second value

Returns:

true if they are equal, false otherwise.

equals

public static boolean equals(double aObj1,
             double aObj2)

Check if two double values are equal. This is necessary, because in some cases, the "==" operator returns wrong results.

Parameters:

aObj1 - First double

aObj2 - Second double

Returns:

true if they are equal, false otherwise.

equals

public static boolean equals(float aObj1,
             float aObj2)

Check if two float values are equal. This is necessary, because in some cases, the "==" operator returns wrong results.

Parameters:

aObj1 - First float

aObj2 - Second float

Returns:

true if they are equal, false otherwise.

equals

public static boolean equals(int aObj1,
             int aObj2)

Check if two values are equal. This method only exists, so that no type differentiation is needed.

Parameters:

aObj1 - First value

aObj2 - Second value

Returns:

true if they are equal, false otherwise.

equals

public static boolean equals(long aObj1,
             long aObj2)

Check if two values are equal. This method only exists, so that no type differentiation is needed.

Parameters:

aObj1 - First value

aObj2 - Second value

Returns:

true if they are equal, false otherwise.

equals

public static boolean equals(short aObj1,
             short aObj2)

Check if two values are equal. This method only exists, so that no type differentiation is needed.

Parameters:

aObj1 - First value

aObj2 - Second value

Returns:

true if they are equal, false otherwise.

equals

public static boolean equals(@Nullable
             Object aObj1,
             @Nullable
             Object aObj2)

Check if two values are equal. This method only exists, so that no type differentiation is needed.

Parameters:

aObj1 - First value

aObj2 - Second value

Returns:

true if they are equal, false otherwise.
