52. Assignment and '?' operator

Program to demonstrate basic assignment operator usage

class AssignmentOperator {    public static void main(String args[])    {       int a;       a=5;       //Here we are using assignment operator '=' to assign value '5' to variable 'a'       System.out.println(a);    }  } Output of this program: 5

Program to demonstrate assignment operator assigning a single value to more than one variable in a single statement

class AssignmentOperator2 {    public static void main(String args[])    {       int a,b,c;       a=b=c=5;    //Here we are using assignment operator '=' to assign value '5' to variables 'a','b' and 'c' in a single statement       System.out.println(a);       System.out.println(b);       System.out.println(c);    }  } 5 5 5

Program to demonstrate '?' operator

class QuestionOperator {    public static void main(String args[])    {       int i=10;       int k= i<0 ? -i: i;    // i<0 is true then -i after the question mark will be assigned to variable 'k' else value of i will be assigned       System.out.println("k="+k);    }  } Output of this program: k=10

Another Program to demonstrate the '?' operator

class QuestionOperator {    public static void main(String args[])    {       int i=-10;       int k= i<0 ? -i: i;     // i<0 is true then -i after the question mark will be assigned to variable 'k' else value of i will be assigned       System.out.println("k="+k);    }  } Output of this program: k=10
