我是java的初学者，我正在尝试逐个字符比较java中的两个字符串，并通过以下代码找到它们有多少不同的字符，但它不起作用，

I am beginner in java, I am trying to compare two strings in java char by char and find how many different chars they have by the following code but it doesn't work,

min is the min between the 2 strings for(int i=0; i<min-1; i++){ s1 = w1.substring(j,j++); s2 = w2.substring(j,j++); if (! s1.equalsIgnoreCase(s2) ){ counter++; } }`

有什么建议吗?

推荐答案

使用这个:

char[] first = w1.toLowerCase().toCharArray(); char[] second = w2.toLowerCase().toCharArray(); int minLength = Math.min(first.length, second.length); for(int i = 0; i < minLength; i++) { if (first[i] != second[i]) { counter++; } }
