java String Builder code example
Example 1: java string builder

System.out.println("String = " + stringBuilder.toString());
Example 2: stringbuilder in java
Java StringBuilder class is used to create
mutable (modifiable) string. The Java
StringBuilder class is same as StringBuffer
class except that it is non-synchronized.
StringBuilder()
creates an empty string Builder with the initial capacity of 16.
StringBuilder(String str)
creates a string Builder with the specified string.
StringBuilder(int length)
creates an empty string Builder with the specified capacity as length.
Example 3: why string builder
StringBuilder is for, well, building strings.
Specifically, building them in a very
performance way. The String class is good
for a lot of things, but it actually has
really terrible performance when assembling
a new string out of smaller string parts
because each new string is a totally new,
reallocated string.
