Equality, Relational, and Conditional Operators >

Equality Operators
==	equal to
!=	not equal to
Relational Operators
>	greater than
>=	greater than or equal to
<	less than
<=	less than or equal to
Conditional Operators
&&	Conditional AND operator1 operator2 Result true true true true false false false true false false false false
||	Conditional OR operator1 operator2 Result true true true true false true false true true false false false
Ternary operator
?:	ternary operator

Program 3.1 to demonstrate equality operators

/** JavaMadeSoEasy.com */ public class EqualityOperatorTest {    public static void main(String[] args) {           int x=4;           int y=2;                     System.out.println(x==y); //false               System.out.println(x!=y); //true    } } /*OUTPUT false true */

Program 3.2 to demonstrate relational operators

/** JavaMadeSoEasy.com */ public class RelationalOperatorTest {    public static void main(String[] args) {           int x=4;           int y=2;           System.out.println(x>y); //true                 System.out.println(x>=y); //true                          System.out.println(x<y); //false           System.out.println(x<=y); //false                     System.out.println(x>=4); //true           System.out.println(y<=2); //true              } } /*OUTPUT true true false false true true */

Program 3.3 to demonstrate conditional operators

/** JavaMadeSoEasy.com */ public class ConditionalOperatorTest {    public static void main(String[] args) {           int x=4;           int y=2;           System.out.println("---------  && -----------");                     System.out.println((x==4) && (y==2)); //true -->> (x==4) returns true, (y==2) also returns true,                                                                      //So,  (true && true) returns true           System.out.println((x==7) && (y==2)); //false -->> (x==7) returns false, so (y==2) is not evaluated.                                                                      //So,  (false && (true/false)) returns false           System.out.println((x==4) && (y==9));  //false -->> (x==4) returns true, but (y==2) returns false.                                                                      //So,  (true && false) returns false           System.out.println("---------  || -----------");                     System.out.println((x==4) || (y==8));  //true -->> (x==4) returns true, so (y==8) is not evaluated.                                                                             //So,  (true || (true/false)) returns true           System.out.println((x==7) || (y==2));   //true -->> (x==7) returns false, (y==2) returns true                                                                             //So,  (false || (true/false)) returns true           System.out.println((x==9) || (y==8)); //false  -->> (x==9) returns false, (y==2) also returns false                                                                             //So,  (false || false) returns false    } } /*OUTPUT ---------  && ----------- true false false ---------  || ----------- true true false */

Program 3.4 to demonstrate ternary operator >

/** JavaMadeSoEasy.com */ public class TernaryConditionalOperatorTest {    public static void main(String[] args) {           int x=3;           System.out.println( (x >4) ?   "x is > 4"   :   "x is < 4" );           System.out.println( (x==3) ?   "x == 3" :   "x != 3" );              } } /*OUTPUT x is < 4 x == 3 */
