But you can do it like this in Java (in C# it's the same, but the method is called Insert): aStringBuilder.insert(0, "newText"); The getChars(int srcBegin, int srcEnd, char[] dst, int dstBegin) method of StringBuilder class copies the characters starting at the given index:srcBegin to index:srcEnd-1 from String contained by StringBuilder into an array of char passed as parameter to function.. StringBuilder comes to rescue. Enlarging the value of this instance would exceed MaxCapacity. It is mutable. "); System.out.println(str); } } chevron_right. Each effectively converts a given datum to a string and then appends or inserts the characters of that string to the string builder. StringBuilder objects are like String objects, except that they can be modified. The char argument is appended to the contents of this StringBuilder sequence.
