判断两个字符串是否是相同字符不同顺序

public static boolean compare(String a,String b){
        byte[] b1 = a.getBytes();
        byte[] b2 = b.getBytes();
        int[] bCount = new int[256];
        for(int i=0;i<256;i++){
            bCount[i] = 0;
        }
        for(int i=0;i<b1.length;i++)
            bCount[b1[i]-'0']++;            
        for(int i=0;i<b2.length;i++)
            bCount[b2[i]-'0']--;
        for(int i=0;i<256;i++){
            if(bCount[i]!=0)
                return false;
        }
        return true;
    }
