小记遇见过的代码小片段

[b]符号分隔拼接字符串[/b]


  @Override
  public String toString() {
    StringBuilder sb = new StringBuilder();
    String sep = "";
    for (Pair<List<String>,Long> pattern : frequentPatterns) {
      sb.append(sep);
      sb.append(pattern.toString());
      sep = ", ";

    }
    return sb.toString();

  }

[b]判断相等[/b]


  @Override
  public boolean equals(Object obj) {
    if (this == obj) {
      return true;
    }
    if (obj == null) {
      return false;
    }
    if (getClass() != obj.getClass()) {
      return false;
    }
    Pattern other = (Pattern) obj;
    // expensive check done only if length and support matches    
    return length == other.length && support == other.support && Arrays.equals(pattern, other.pattern);
  }
