Explain to someone how you swap 2 values in Java? You need three stalls to swap variables. Stall1, Stall 2 and a Tempstall. First you assign Stall1 to the tempstall. then you assign stall2 to the now empty (assigned to the tempstall) stall1. lastly you assign the tempstall which contains the original stall1 variable to the stall2. Here’s the code.
static void swap(String s1, String s2){
String temp = s1;
s1=s2;
s2=temp;
}
public static void main(String[] args) {
String s1 = "Hello", s2 = "world";
swap(s1, s2);
System.out.println(s1 + s2);
}
