Parameter(s):

参数：

• It does not accept any parameter.

  它不接受任何参数。

Return value:

返回值：

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

该方法的返回类型为long ，它返回这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
