To clear or empty a StringBuilder in Java, you can use the setLength method and set the length to 0. This will remove all characters from the StringBuilder and reset its length to 0. Here's an example of how to use the setLength method to clear a StringBuilder: StringBuilder sb = new...
If you have clear ASCII separator which you have in your case (\n), you'll not need to care about incomplete string as this character maps to singlebyte (and vice versa). So just search for '\n' byte in your input and read and convert anything before into String. Loop u...
public static String getFriendlyTime(Date dateTime) { StringBuffer sb = new StringBuffer(); Date current = Calendar.getInstance().getTime(); long diffInSeconds = (current.getTime() - dateTime.getTime()) / 1000; /*long diff[] = new long[]{0, 0, 0, 0}; /* sec * diff[3] = (...
In an attempt to solve the problem by simulation, we choose to associate to each member a vector of n integers. Position i of the vector will have the value 1 if the member is already sitting on the chair I and 0 otherwise. The simulation ends when the vector of each member is set ...
We need to use and make StringBuilder or StringBuffer a way of life instead of String. And it is better to accumulate as few logs as possible. However, we know that there are some cases we cannot help. We have seen that XML and JSON parsing use the most memory. Even though we use ...
Then that buffer is converted to a String and passed to a message() function, which is the abstraction allowing different classes to receive data. The contents of that String are then copied into a StringBuffer instance, which is the improvement I contributed 5 years ago. At a rate of 30...
There is a saying, "many a little makes a mickle." We need to take care of small things, or they will add up and become something big which is difficult to manage. We need to use and make StringBuilder or StringBuffer a way of life instead of ...

Here is our Java program, which checks if a given String is palindrome or not. The program is simple, and here are steps to find palindrome String : 1) Reverse the given String 2) Check if the reverse of String is equal to itself; if yes, then given String is a palindrome. In our...
