java reverse

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

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

  reverse()方法在java.lang包中可用。

• reverse() method is used to returns the value generated by reversing the order of bits in binary 2's complement denotation of the given argument.

  reverse()方法用于返回通过反转给定参数的二进制2的补码表示形式的位顺序生成的值。

• reverse() 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.

  reverse()方法是一个静态方法，它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，那么我们也不会收到错误。

• reverse() method does not throw an exception at the time of reversing the order of bits.

  reverse()方法在反转位顺序时不会引发异常。

Syntax:

句法：

    public static int reverse(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, it returns an integer value generated by reversing the bits order in 2's complement of the given integer value.

此方法的返回类型为int ，它返回一个整数值，该整数值是通过反转给定整数值的2的补码中的位顺序而生成的。

Example:

例：

// Java program to demonstrate the example
// of reverse(int value) method of Integer class
public class ReverseOfIntegerClass {public static void main(String[] args) {int value = 1296;
// Display value
System.out.println("value:" + value);
// 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 value generated by reversing the
// order of the bits in the given argument value
// by calling Integer.reverse(value)
System.out.println("Integer.reverse(value): " + Integer.reverse(value));
}
}

Output

输出量

value:1296
Integer.toBinaryString(value): 10100010000
Integer.reverse(value): 144703488
