長類lowerOneBit()方法 (Long class lowestOneBit() method)

• lowestOneBit() method is available in java.lang package.

  minimumOneBit()方法在java.lang包中可用。

• lowestOneBit() method is used to find at most only single 1’s bit from the rightmost side one bit in the path of the lowest order of the given parameter [value] of long type.

  minimumOneBit()方法用于在long類型給定參數[value]的最低順序路徑中，從最右側最多只能找到單個1位。

• lowestOneBit() method is a static method, it is accessible with the class name too and if we try to access the method with the class object then also we will not get an error.

  minimumOneBit()方法是一個靜態方法，也可以使用類名進行訪問，如果我們嘗試使用類對象訪問該方法，那么也不會出錯。

• lowestOneBit() method does not throw an exception at the time of determining the lowest order bit in a single digit.

  minimumOneBit()方法在確定一位數字的最低順序位時不會引發異常。

Syntax:

句法：

    public static long lowestOneBit (long value);

Parameter(s):

參數：

• long value – represents the long value to be parsed.

  long value –表示要解析的long值。

Return value:

返回值：

The return type of this method is long, it returns the long value based on the following cases,

此方法的返回類型為long ，它根據以下情況返回long值：

• it returns at most only single 1’s bit in the path of rightmost side one bit of the given long value.

  它在最右邊的路徑中最多返回單個1的位，即給定long值的一位。

• Else, if the given argument is zero then, it returns the value 0.

  否則，如果給定參數為零，則返回值0。

Example:

例：

// Java program to demonstrate the example 
// of lowestOneBit (long value) method of Long class
public class LowestOneBitOfLongClass {
public static void main(String[] args) {
long value = 1296;
// It returns the string representation of the given unsigned 
// long value denoted by the argument in binary by calling
// Long.toBinaryString(value)
System.out.println("Long.toBinaryString(value): " + Long.toBinaryString(value));
// It returns the number with atmost 1's bits in the path of rightmost side 
// one bit in the given argument 'value' by calling Long.lowestOneBit(value)
System.out.println("Long.lowestOneBit(value): " + Long.lowestOneBit(value));
}
}

Output

輸出量

Long.toBinaryString(value): 10100010000
Long.lowestOneBit(value): 16
