类型不匹配:无法从整数转换为布尔值 [英] Type mismatch: cannot convert from integer to boolean

问题描述

public boolean clearSelection() {
    int i = 0;
    if (!this.m_SelectedComps.isEmpty()) {
        i = 1;
        Iterator localIterator = this.m_SelectedComps.iterator();
        while (localIterator.hasNext())
            ((AnnotComponent) localIterator.next()).remove();
        this.m_SelectedComps.clear();
    }

    return i;
}

如何将整数转换为布尔值?

How to convert the integer to boolean?

推荐答案

试试这个返回

return i == 1;

或者只是使用布尔值开始(使用更好的名称):

or just use a boolean to start (with a better name):

 public boolean clearSelection()
  {
    boolean flag = false;
    if (!this.m_SelectedComps.isEmpty())
    {
      flag = true;
      Iterator localIterator = this.m_SelectedComps.iterator();
      while (localIterator.hasNext())
        ((AnnotComponent)localIterator.next()).remove();
      this.m_SelectedComps.clear();
    }
    return flag;
  }

它继续让我感到困惑为什么人们使用 i - 一个可怕的变量名.看起来像 1 并没有传达任何含义.

It continues to mystify me why people use i -- a horrible variable name. Looks like 1 and does not convey any meaning.
