c)Then compare the first character with the next characters to it. If matched then replace the matched elements with “*”. Repeat these b,c steps for all elements of the string. 4)Remove all ‘*’ from the string as follows.
Write a Java program to count the frequency of each character in a string and then output the string with duplicates removed. Write a Java program to remove duplicate letters from a string while preserving the order of their first appearance. ...
在使用ArrayList移除特定字符时，直接调用list.remove('的')只能移除第一个匹配的字符，并且只能移除一个。如果需要移除列表中所有的'的'，可以使用Iterator进行遍历，并通过调用Iterator的remove方法来移除匹配的元素。代码示例如下：for(Iterator iterator = list.iterator();iterator.hasNext();) { char c...
