在Java中将给定的二进制字符串转换为整数和反之​​亦然

Question

I'm trying to convert a binary number in string into integer and vice versa . For eg -

Binary = 001 Integer - 1 I know i can do this like

int decimal = 0;  
int n = 0;  
while(true){  
  if(binary == 0){  
    break;  
  } else {  
      int temp = binary%10;  
      decimal += temp*Math.pow(2, n);  
      binary = binary/10;  
      n++;  
   }  
}  
return decimal;

I want conversions between these two using some direct functions. Can anyone please help me. Thankyou.

Answer 1

So here is a simple answer for this. To Convert a Binary String let us say eg S= "001" to Integer use - Integer.parse(S,2) and to convert a Integer back to Binary String use- Integer.toBinaryString(num)

Hope This Helps. Thankyou.
