Method Detail

valueOf

public static java.lang.Boolean valueOf(boolean value)

Get a Boolean from a boolean, equivalent to the java 1.4 method Boolean.valueOf(boolean)

Parameters:

value - the boolean

Returns:

the Boolean equivalent

equals

public static boolean equals(double a,
                             double b)

Test the equality of two doubles by converting their values into IEEE 754 floating-point "double format" long values.

Parameters:

a - Double to check equality with.

b - Double to check equality with.

Returns:

True if a equals b.

equals

public static boolean equals(float a,
                             float b)

Test the equality of two doubles by converting their values into IEEE 754 floating-point "single precision" bit layouts.

Parameters:

a - Float to check equality with.

b - Float to check equality with.

Returns:

True if a equals b.

equals

public static boolean equals(byte[] a,
                             int abegin,
                             byte[] b,
                             int bbegin,
                             int length)

Test the equality of a given sub-section of two byte arrays.

Parameters:

a - The first byte array.

abegin - The begining index of the first byte array.

b - The second byte array.

bbegin - The begining index of the second byte array.

length - The length of the sub-section.

Returns:

True if sub-sections are equal.

equals

public static boolean equals(byte[] a,
                             byte[] b)

Test the equality of two byte arrays.

Parameters:

a - The first byte array.

b - The second byte array.

Returns:

True if the byte arrays are equal.
