Let us see the below example:
Write a program to remove the leading and trailing spaces from a string using the trim()
Program 22
method.
1 class stringTrim
2 {
3 public static void main(String[] args)
4 {
5 String sen1= " Computer Science ";
6 System.out.println(sen1.trim());
7 }
8 }
The output of the preceding program is as follows:

10.3 STRINGBUFFER CLASS
The StringBuffer class is used to create sufficient space in the memory to store a string. This space in memory can be
changed as required. If the string is less than the size defined, the extra space will contain an extra value. Let us learn
about some of the commonly used methods of the StringBuffer class.
10.3.1 The append() Method
We use the append() method to concatenate a string at the end of another string. The syntax of the append() method is:
StringBuffer string_object.append(StringBuffer variable);
Let us see the below example:
Program 23 Write a program to append one StringBuffer to another and print the result.
1 class stringAppend
2 {
3 public static void main(String[] args)
4 {
5 StringBuffer s1= new StringBuffer("Computer");
6 StringBuffer s2= new StringBuffer("Science");
7 s1.append(s2);
8 System.out.println(s1);
9 }
