两个字符串是变位词

anagram(s, t)

"abcd"

"dcab"

true

public class Solution {
/**
* @param s: The first string
* @param b: The second string
* @return true or false
*/
public boolean anagram(String s, String t) {
// write your code here
char[] sc = s.toCharArray();  //将字符串转换为字符数组
char[] tc = t.toCharArray();
Arrays.sort(sc);
Arrays.sort(tc);
String scc = new String(sc);  //字符数组再转换为字符串
String tcc = new String(tc);
return scc.equals(tcc);
}
};
