比较字符串的方法

可以讲字符串转换为字符数组，举个简单的例子如下，你一看就懂：

public class MyTest1 {
public static void main(String[] args) {
String str = “I am a String”;
char arr[] = str.toCharArray();
for (int i = 0; i < arr.length; i++)
System.out.println(“arr[“ + i + “]=” + arr[i]);
}
}

public class TT
{
private static int compare(String f, String s)
{
int count = 0;
for ( int i = 0; i < f.length (); i++ )
{
for ( int j = 0; j < s.length (); j++ )
{
if (f.charAt (i) == s.charAt (j))
{
count++;
}
}
}
return count;
}
public static void main ( String[] args )
{
System.out.println (compare (“67821”, “12345”));
}
}
