//One way of doing concatenation

// Java program to demonstrate
// working of concat() method
class Gfg {
public static void main(String args[])
{
String s = "Gfg";
s = s.concat("! is the best.");
System.out.println(s);
}
}string concatenation in java
String s="Sachin"+" Tendulkar";
System.out.println(s);//Sachin Tendulkar

String strconcat3=strconcat2.concat(strconcat);
-By StringBuffer
-String strconcat= new StringBuilder().append("matt")
.append("damon").toString();
-By StringBuilder
- String strconcat2= new StringBuffer()
