在本教程中,我们将java 程序编写为相加两个二进制数。二进制数系统只有两个符号 0 和 1 所以二进制数只包含 0 和 1。在我们编写相加程序之前,让我们看看我们如何在纸上相加,如下图所示:
示例:在 Java 中相加二进制数
在这个程序中,我们使用Scanner
从用户获取输入(用户输入我们需要相加的两个二进制数),然后我们使用while
循环逐位相加它们,并将结果存储在一个数组中。
import java.util.Scanner;
public class JavaExample {
public static void main(String[] args)
{
//Two variables to hold two input binary numbers
long b1, b2;
int i = 0, carry = 0;
//This is to hold the output binary number
int[] sum = new int[10];
//To read the input binary numbers entered by user
Scanner scanner = new Scanner(System.in);
//getting first binary number from user
System.out.print("Enter first binary number: ");
b1 = scanner.nextLong();
//getting second binary number from user
System.out.print("Enter second binary number: ");
b2 = scanner.nextLong();
//closing scanner after use to avoid memory leak
scanner.close();
while (b1 != 0 || b2 != 0)
{
sum[i++] = (int)((b1 % 10 + b2 % 10 + carry) % 2);
carry = (int)((b1 % 10 + b2 % 10 + carry) / 2);
b1 = b1 / 10;
b2 = b2 / 10;
}
if (carry != 0) {
sum[i++] = carry;
}
--i;
System.out.print("输出: ");
while (i >= 0) {
System.out.print(sum[i--]);
}
System.out.print("\n");
}
}
输出:
Enter first binary number: 11100
Enter second binary number: 10101
输出: 110001
