Parameter(s):

參數：

• It does not accept any parameter.

  它不接受任何參數。

Return value:

返回值：

The return type of the method is long, it returns least significant 64 bits of these 128 bits.

該方法的返回類型為long ，它返回這128位中的最低有效64位。

Example:

例：

// Java program to demonstrate the example 
// of long getLeastSignificantBits() method of UUID 
import java.util.*;
public class GetLeastSignificantBitsOfUUID {
public static void main(String[] args) {
// Instantiate UUID 
UUID uuid = UUID.fromString("46400000-8cc0-11bd-b43e-10d46e4ef14d");
// By using getLeastSignificantBits() method
// is to returns the least significant bits
long least_sb = uuid.getLeastSignificantBits();
// Display least_sb
System.out.println(" uuid.getLeastSignificantBits(): " + least_sb);
}
}

Output

輸出量

uuid.getLeastSignificantBits(): -5458907193756683955
