Operator Concept in Java:-
It is used to perform operations using operand, the operand can be variable, constant, or literals.
int a=10; a is the variable,10 is the literals
System.out.println(100+200) ; 100 ,200 is called literals.
.....................................................................................................................................
The operator will be called by a symbol but defined as a method, for example, if we use + operator then + is the symbol but it has defined as +() method
Operator +(param1)
{
}
Type of Operator:-
1) Unary Operator:- This operator will work using a single operand.
1.1 Increment:- increase current value by one
1.1.1 Post Increment:- operand++
First complete other operation(print, assign) then increase the value
int a=5;
int b;
b=a++;
System.out.println(a,",",b);
The expected output is b=5 and a=6
1.1.2 Pre Increment:- ++operand
First increase value by one after that complete other operation
int a=5;
int b;
b=++a;
System.out.println(a,",",b);
class Incre
{
public static void main(String args[])
{
int a=2,b=3;
System.out.println(a++ + "," + ++b );
}
}
The expected output is a=2 and b=4
Example of Increment |Decrement:-
class Incre
{
public static void main(String args[])
{
int a=2,b=3;
b= a++ + a++ + a++ + a++;
// 14 2 3 4 5 6
System.out.println(a + "," + b);
}
}
class Incre
{
public static void main(String args[])
{
int a=2,b=3;
b = ++a + a++ + ++a + a++;
// 16 3 3 5 5 6
System.out.println(a + "," + b);
}
}
1.2 Decrement
class Incre
{
public static void main(String args[])
{
int a=12,b=3;
b = --a + a-- + --a + a--;
// 40 11 11 9 9 8
System.out.println(a + "," + b);
}
}
2) Binary Operator:-
It requires a minimum of two operands to perform the operation.
2.1 ) Arithmetic Operator:- +,-,*,/,%
2.2) Conditional Operator:- <,>,<=,>=
2.3) Comparison Operator:-
2.,3.1 Data Comparision Operator ==
2.3.2 Address Comparaision Operator equals():-
class Eqldemo
{
public static void main(String args[])
{
String s ="hello";
String s1 = new String("hello");
if(s.equals(s1))
{
System.out.println("equall");
}
else
{
System.out.println("not equall");
}
}
}
2.4) Assignment Operator
2.4.1) Simple =
2.4.2) Complex Assignment or Shorthand Operator
+=,-=,*=,/=,%=
a+=7 or a=a+7
a-=3 or a=a-3
a+=7 or a=a+7
a-=3 or a=a-3
class Eqldemo
2.5) Logical Operator:- &&, ||, !
&& :- it returns true when all condition will be true
||:- it returns true when a particular condition will be true
!:- it is the opposite of a true statement and converted the result into a false statement
{
public static void main(String args[])
{
int a=5;
a+=9; //14
a-=3; //11
a*=12; //132
a/=17; //7
a%=3; //1
a*=23; //23
System.out.println(a);
}
}
2.5) Logical Operator:- &&, ||, !
&& :- it returns true when all condition will be true
||:- it returns true when a particular condition will be true
!:- it is the opposite of a true statement and converted the result into a false statement
a=9
a>2 && a<5
a>2 or a<5
a>2 && a<5
a>2 or a<5
Assignment:-
1) WAP to convert Decimal to binary and binary to decimal
2) WAP to perform addition of number without using + operator?
3) Ternary Operator:-
It is used to solve condition-based problems using a single-line statement. Ternary operators contain a minimum of three operators to solve statements.
res = (condition)? true : false;
WAP to check that the entered number is even or odd using the ternary operator
class CheckEvenOdd
{
public static void main(String args[])
{

String s = (num%2==0)?"Even":"Odd";
System.out.println(s);
}
}
class Checkgreater
{

{

String s = (a>b)?"a is greater":"b is greater";

}

String s = (year%400==0) || (year%100!=0 && year%4==0)? "leap year": "not a
