try {   
            PrintWriter pw = response.getWriter();   
               
            int x = 98;   
               
            pw.write(x);   
               
            pw.print(x);   
               
        } catch (IOException e) {   
            e.printStackTrace();   
        }  
try {
   PrintWriter pw = response.getWriter();
   
   int x = 98;
   
   pw.write(x);
   
   pw.print(x);
   
  } catch (IOException e) {
   e.printStackTrace();
  }

輸出：b  98

最終都是重寫了抽象類Writer裡面的write方法
print方法可以將各種型別的資料轉換成字串的形式輸出。過載的write方法只能輸出字元、字元陣列、字串等與字元相關的資料。
檢視一下原始碼(java.io.PrintWriter)：

1：write方法：

  view plaincopy to clipboardprint?
 public void write(int c) {   
try {   
    synchronized (lock) {   
 ensureOpen();   
 out.write(c);   
    }   
}   
catch (InterruptedIOException x) {   
    Thread.currentThread().interrupt();   
}   
catch (IOException x) {   
    trouble = true;   
}   
   }  
  public void write(int c) {
 try {
     synchronized (lock) {
  ensureOpen();
  out.write(c);
     }
 }
 catch (InterruptedIOException x) {
     Thread.currentThread().interrupt();
 }
 catch (IOException x) {
     trouble = true;
 }
    }
 

2：print方法：

  view plaincopy to clipboardprint?
public void print(int i) {   
rite(String.valueOf(i));   
  }
