The answer is Multitasking. NOS (Network Operating System) has the ability to execute more than one program at a time. It allows different programs to operate on the CPU, effectively giving each program a virtual copy of the CPU while preventing the program from directly manipulating the hardware. The NOS switches the CPU time from one task to another in order to create the idea that several tasks are being executed at the same time, but in reality, only one program is being executed.
Answer:

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.
