Operador en Java Es un símbolo que se utiliza para realizar operaciones. Por ejemplo: +, -, *, / etc.

Hay muchos tipos de operadores en Java que se detallan a continuación:

• operador unario,
• operador aritmético,
• operador de turno,
• operador relacional,
• operador bit a bit,
• operador lógico,
• Operador ternario y
• Operador de Asignación.

Precedencia del operador Java

Operador unario de Java

Los operadores unarios de Java requieren sólo un operando. Los operadores unarios se utilizan para realizar diversas operaciones, es decir:

• incrementar/disminuir un valor en uno
• negando una expresión
• invirtiendo el valor de un booleano

Ejemplo de operador unario de Java: ++ y --

 public class OperatorExample{ public static void main(String args[]){ int x=10; System.out.println(x++);//10 (11) System.out.println(++x);//12 System.out.println(x--);//12 (11) System.out.println(--x);//10 }}

Ejemplo 2 de operador unario de Java: ++ y --

 public class OperatorExample{ public static void main(String args[]){ int a=10; int b=10; System.out.println(a++ + ++a);//10+12=22 System.out.println(b++ + b++);//10+11=21 }} 

Producción:

 22 21 

Ejemplo de operador unario de Java: ~ y !

 public class OperatorExample{ public static void main(String args[]){ int a=10; int b=-10; boolean c=true; boolean d=false; System.out.println(~a);//-11 (minus of total positive value which starts from 0) System.out.println(~b);//9 (positive of total minus, positive starts from 0) System.out.println(!c);//false (opposite of boolean value) System.out.println(!d);//true }} 

Producción:

 -11 9 false true 

Operadores aritméticos de Java

Los operadores aritméticos de Java se utilizan para realizar sumas, restas, multiplicaciones y divisiones. Actúan como operaciones matemáticas básicas.

Ejemplo de operador aritmético de Java

 public class OperatorExample{ public static void main(String args[]){ int a=10; int b=5; System.out.println(a+b);//15 System.out.println(a-b);//5 System.out.println(a*b);//50 System.out.println(a/b);//2 System.out.println(a%b);//0 }}

Ejemplo de operador aritmético de Java: expresión

 public class OperatorExample{ public static void main(String args[]){ System.out.println(10*10/5+3-1*4/2); }}

Operador de desplazamiento a la izquierda de Java

El operador de desplazamiento a la izquierda de Java << se utiliza para desplazar todos los bits de un valor al lado izquierdo un número específico de veces.

Operador ternario de Java

El operador ternario de Java se utiliza como reemplazo de una línea para la declaración if-then-else y se usa mucho en la programación Java. Es el único operador condicional que requiere tres operandos.
