El método java.lang.string.join() concatena los elementos dados con el delimitador y devuelve la string concatenada. Tenga en cuenta que si un elemento es nulo, entonces se agrega nulo. El método join() está incluido en la string java desde JDK 1.8 .
Hay dos tipos de métodos join() en la string java.
Sintaxis:
public static String join(CharSequence deli, CharSequence... ele) and public static String join (CharSequence deli, Iterable<? extends CharSequence> ele) Parameters: deli- delimiter to be attached with each element ele- string or char to be attached with delimiter Returns : string joined with delimiter.
// Java program to demonstrate
// working of join() method
class Gfg1 {
public static void main(String args[])
{
// delimiter is "<" and elements are "Four", "Five", "Six", "Seven"
String gfg1 = String.join(" < ", "Four", "Five", "Six", "Seven");
System.out.println(gfg1);
}
}
Producción:
Four < Five < Six < Seven
// Java program to demonstrate
// working of join() method
class Gfg2 {
public static void main(String args[])
{
// delimiter is " " and elements are "My",
// "name", "is", "Niraj", "Pandey"
String gfg2 = String.join(" ", "My", "name", "is", "Niraj", "Pandey");
System.out.println(gfg2);
}
}
Producción:
My name is Niraj Pandey
// Java program to demonstrate
// working of join() method
class Gfg3 {
public static void main(String args[])
{
// delimiter is "->" and elements are "Wake up",
// "Eat", "Play", "Sleep", "Wake up"
String gfg3 = String.join("-> ", "Wake up", "Eat",
"Play", "Sleep", "Wake up");
System.out.println(gfg3);
}
}
