If the extra character is always at end then....

public static void main(String[] args) {

		String A = "abcjdfdkjsf";

		String B = "abcjdfdkjsfg";
		
		if(A.contains(B)) {
			System.out.println(A.substring(B.length()));
		}else if(B.contains(A)) {
			System.out.println(B.substring(A.length()));
		}
	}

"""xor two strings together"""
res = 0
# end and xor with res
for i in range(len(s)) :
# xor with res
res =res ^ (ord)(s[i])
# end and xor with res
for i in range(len(t)) :
# xor with res
res = res ^ (ord)(t[i])
