Answer:
//here is code in java.
import java.util.*;
class Solution
{
// main method of class
public static void main (String[] args) throws java.lang.Exception
{
try{
// declare an initialize first string variables
String st1="hello";
// declare an initialize first string variables
String st2="world";
// create another string variable
String st3;
// exchange the value of both string variables
st3=st1;
st1=st2;
st2=st3;
System.out.println("value of first String after exchange: "+st1);
System.out.println("value of second String after exchange: "+st2);
}catch(Exception ex){
return;}
}
}
Explanation:
declare and initialize two string variables.Create another string variable "st3". first assign value of "st1" to "st3" after then value of "st2" to "st1" and then assign value of "st3" to "st2". This will exchange the values of both the string.
Output:
value of first String after exchange: world
value of second String after exchange: hello
Answer: Joystick is the only one that makes sense, a stylus and digitizer are both used on drawing tablets, not computer games.
Answer:
The following are code in the Java Programming Language.
//define boolean type function
boolean isReverse(int ar[], int b[])
{
//declare integer type variable
int x;
//set the for loop
for (x=0; x < ar.length && ar[x] == b[ar.length-1-x]; x++);
return x == ar.length;
}
Explanation:
<u>The following are the description of the code</u>.
In the above code that is written in the Java Programming Language, we define the boolean data type function that is 'is Reverse()' and pass two array integer data type arguments that is 'ar', 'b' in the then, declare integer data type variable that is 'x'. Set the for loop that the boolean type value is true or false.
