Example of Java String concat() :
concat() method is used to join two strings. It concatenates one string to the end of another string. This method is defined as below :
public String concat(String s)
It takes one string as the parameter. It concatenates this string to the end of the other string and returns the new string. A string is immutable in Java. So, it creates and returns the new string.
Example using two strings :
class Example{
public static void main(String[] args) {
String str1 = "code";
String str2 = "color";
String str = str1.concat(str2);
System.out.println(str);
}
}
Output :
codecolor
Example using multiple strings :
We can also use the concat method to join multiple strings. concat() method returns one new string. We can call concat() method on this returned string.
class Example{
public static void main(String[] args) {
String str1 = "code";
String str2 = "vs";
String str3 = "color";
String str = str1.concat(str2).concat(str3);
System.out.println(str);
}
}
Output :
codevscolor
