The position that holds the last character istext.length()-1. We used thetoString()method to get the string from ourStringBufferobject. Please bear in mind thatdeleteCharAt(int index)throwsStringIndexOutOfBoundsExceptionif the specified index is negative or greater than the length of the string....
StringUtils.substring()requires three parameters: a givenString,an index of the first character (in our case it will be 0 always), and the index of the penultimate character. Again, we can simply use thelength()method and subtract1: String TEST_STRING = "abcdef"; StringUtils.substring(TEST...

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...
scala> StringUtils.chop("abc") val res0: String = ab The method behaves very similarly to the init() method we saw before, as it removes the last character of the String. This lib was written in Java, so it may not be as idiomatic, but it still shows very useful. 3. Conclusion ...

A string is nothing but an array of characters. The value of a string is determined by the terminating character. Its value is considered to be 0. As you can see in the given example, you need to enter the string first up. The string entered here is“hello world” ...

b: new character which needs to replace the old character. Return Value: Resultant string after replacements. In this approach, we loop over the string and find whether the current character is non-alphanumeric or not using its ASCII value (as we have already done in the last method). If...
