整数类highestOneBit()方法 (Integer class highestOneBit() method)

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

  maximumOneBit()方法在java.lang包中可用。

• highestOneBit() method is used to find almost only single 1's bit from the leftmost side one bit in the path of the highest order of the given parameter [value] of integer type.

  maximumOneBit()方法用于在整数类型的给定参数[value]的最高阶路径中，从最左侧的一位开始几乎只查找一位。

• highestOneBit() 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.

  maximumOneBit()方法是一个静态方法，也可以使用类名进行访问，如果我们尝试使用类对象访问该方法，则也不会出错。

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

  maximumOneBit()方法在确定一位数的最高位时不会引发异常。

Syntax:

句法：

    public static int highestOneBit (int value);

Parameter(s):

参数：

• int value – represents the integer value to be parsed.

  int value –表示要解析的整数值。

Return value:

返回值：

The return type of this method is int, If the given argument is non-zero then, it returns at most only single 1's bit in the path of leftmost side one bit of the given integer value. If the given argument is zero then, it returns the value 0.

此方法的返回类型为int ，如果给定参数为非零，则它在给定整数值的最左侧一位的路径中最多仅返回单个1的位。 如果给定参数为零，则返回值0。

Example:

例：

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

Output

输出量

Integer.toBinaryString(value): 10100010000
Integer.highestOneBit(value): 1024
