本文介绍如何在 Java 中执行二进制加法。

Java 中的二进制数加法

二进制数是 1 和 0 的组合，与算术数不同，相加的方式不同。 二进制数的加法规则为：

0 + 0 = 0
0 + 1 = 1
1 + 0 = 1
1 + 1 = 10. For this, the 1 will carry forward.
1 (carry forwarded) + 1 + 1 = 11 and the 1 will carry forward again.

让我们尝试根据这些规则实现一个可以执行二进制加法的程序：

package jiyik;

import java.util.Scanner;
public class Example {
    public static void main(String[] args){
        long Binary_Number1;
        long Binary_Number2;
        int x = 0;
        int Carry_Forward = 0;

        //The array to hold the result
        int[] Binary_Sum = new int[10];

        //To take the inputs
        Scanner Input_Scanner = new Scanner(System.in);

        System.out.print("Please enter the first binary number: ");
        Binary_Number1 = Input_Scanner.nextLong();
        System.out.print("Please enter the second binary number: ");
        Binary_Number2 = Input_Scanner.nextLong();

        //closing scanner
        Input_Scanner.close();
        while (Binary_Number1 != 0 || Binary_Number2 != 0) {
            Binary_Sum[x++] = (int)((Binary_Number1 % 10 + Binary_Number2 % 10 + Carry_Forward) % 2);
            Carry_Forward = (int)((Binary_Number1 % 10 + Binary_Number2 % 10 + Carry_Forward) / 2);
            Binary_Number1 = Binary_Number1 / 10;
            Binary_Number2 = Binary_Number2 / 10;
        }
        if (Carry_Forward != 0) {
            Binary_Sum[x++] = Carry_Forward;
        }
        --x;
        System.out.print("The result for addition is: ");
        while (x >= 0) {
            System.out.print(Binary_Sum[x--]);
        }
        System.out.print("\n");
    }
}

上面的代码将获取两个二进制数的输入并将它们相加。 查看输出：

Please enter the first binary number: 1010101
Please enter the second binary number: 111111
The result for addition is: 10010100
