replacedemo.java

java2参考大全上的例子的源码和自己的理解.

package replace;

/**
 输出如下所示：
 After replace: This was a test.
 */

// Demonstrate replace()
class replaceDemo {
  public static void main(String args[]) {
    StringBuffer sb = new StringBuffer("This is a test.");

    sb.replace(5, 7, "was");
    System.out.println("After replace: " + sb);
  }
}
