Java StringCharacterIterator equals()方法及实例

Java中 java.text .StringCharacterIterator类 的 equals() 方法用于检查此StringCharacterIterator与指定的StringCharacterIterator是否相等。这个方法接收一个StringCharacterIterator实例，将其与这个StringCharacterIterator进行比较，并返回一个代表相同的布尔值。

语法。

public boolean equals(Object obj)

参数。这个方法接受一个参数 obj ，它是要与这个StringCharacterIterator进行平等检查的StringCharacterIterator。

返回值。该方法返回一个 布尔值 ，告诉你这个StringCharacterIterator是否等于指定的对象。

异常。这个方法不抛出任何异常。

程序。

// Java program to demonstrate// the above method  import java.text.*;import java.util.*;  public class StringCharacterIteratorDemo {    public static void main(String[] args)    {          StringCharacterIterator sci1            = new StringCharacterIterator(                "GeeksforGeeks");          System.out.println("StringCharacterIterator 1: "                           + sci1);          StringCharacterIterator sci2            = new StringCharacterIterator(                "Geeks for Geeks");          System.out.println("StringCharacterIterator 2: "                           + sci2);          StringCharacterIterator sci3            = (StringCharacterIterator)sci1                  .clone();          System.out.println("StringCharacterIterator 3: "                           + sci3);          System.out.println("Comparing DFS 1 and DFS 2: "                           + sci1.equals(sci2));          System.out.println("Comparing DFS 2 and DFS 3: "                           + sci2.equals(sci3));          System.out.println("Comparing DFS 1 and DFS 3: "                           + sci1.equals(sci3));    }}

输出:

StringCharacterIterator 1: java.text.StringCharacterIterator@bd43b778StringCharacterIterator 2: java.text.StringCharacterIterator@ac5740a8StringCharacterIterator 3: java.text.StringCharacterIterator@bd43b778Comparing DFS 1 and DFS 2: falseComparing DFS 2 and DFS 3: falseComparing DFS 1 and DFS 3: true
