Operators in Java and its Types
Operators are the constructs that can manipulate the values of the operands. Consider the expression 2 + 3 = 5, here 2 and 3 are operands and + is called operator. In this article on operators, the goal is to get you the expertise required to get started and work with operators in Java.
Java supports the following types of operators:
- Arithmetic Operators
- Assignment Operators
- Logical Operators
- Relational Operators
- Unary Operators
- Bitwise Operators
- Ternary Operators
- Shift Operators
Let’s focus on each of these operators one by one.
Arithmetic Operators in Java
Arithmetic Operators are used to performing mathematical operations like addition, subtraction, etc. Assume that A = 10 and B = 20 for the below table.
Consider the below example:
package Edureka;
public class ArithmeticOperators {
public static void main(String[] args) {
int A = 10;
int B = 20;
System.out.println(A + B);
System.out.println(A - B);
System.out.println(A * B);
System.out.println(A / B);
System.out.println(A % B);
}
}Output:
30
-10
200
0
10
Assignment Operators in Java
An Assignment Operator is an operator used to assign a new value to a variable. Assume A = 10 and B = 20 for the below table.
Consider the below example:
package Edureka;public class JavaOperators {
public static void main(String[] args) {
int a = 10;
int b=20;
int c;
System.out.println(c = a); // Output =10
System.out.println(b += a);// Output=30
System.out.println(b -= a);// Output=20
System.out.println(b *= a);// Output=200
System.out.println(b /= a);// Output=2
System.out.println(b %= a);// Output=0
System.out.println(b ^= a);// Output=0
}
}
Moving ahead in Java operator's tutorial, let’s see what are comparison operators.
Relational Operators in Java
These operators compare the values on either side of them and decide the relation among them. Assume A = 10 and B = 20.
Consider the below example:
package Edureka;public class JavaOperators {
public static void main(String[] args) {
int a = 10;
int b=20;
System.out.println(a == b); // returns false because 10 is not equal to 20
System.out.println(a != b); // returns true because 10 is not equal to 20
System.out.println(a > b); // returns false
System.out.println(a < b); // returns true
System.out.println(a >= b); // returns false
System.out.println(a <= b); // returns true }}
Next up, let’s focus on logical operators in Java.
Logical Operators in Java
The following are the Logical operators present in Java:
Consider the below example:
package Edureka;public class JavaOperators {
public static void main(String[] args) {
int a = 10;
System.out.println(a<10 & a<20); //returns false
System.out.println(a<10 || a<20); //returns true
System.out.println(!(a<10 & a<20)); //returns true
}
}
Now let’s see unary operators in Java.
Unary Operator in Java
Unary operators are the one that needs a single operand and are used to increment a value, decrement or negate a value.
Consider the following example:
package Edureka;public class JavaOperators {
public static void main(String[] args) {
int a = 10;
boolean b=true;
System.out.println(a++); //returns 11
System.out.println(++a);
System.out.println(a--);
System.out.println(--a);
System.out.println(!b); // returns false }}
Moving ahead, let’s understand bitwise operator in Java
Bitwise Operator in Java
Bitwise operations directly manipulate bits. In all computers, numbers are represented with bits, a series of zeros and ones. In fact, pretty much everything in a computer is represented by bits. Assume that A = 10 and B = 20 for the below table.
Consider the example shown below:
package Edureka;public class JavaOperators {
public static void main(String[] args) {
int a = 58; //111010
int b=13; //1101
System.out.println(a&b); //returns 8 = 1000
System.out.println(a|b); //63=111111
System.out.println(a^b); //55=11011
System.out.println(~a); //-59
}
}
Next up, let’s focus on the ternary operator in Java
Ternary Operators in Java
The ternary operator is a conditional operator that decreases the length of code while performing comparisons and conditionals. This method is an alternative for using if-else and nested if-else statements. The order of execution for this operator is from left to right.
Syntax:
(Condition) ? (Statement1) : (Statement2);- Condition: It is the expression to be evaluated which returns a boolean value.
- Statement 1:It is the statement to be executed if the condition results in a true state.
- Statement 2:It is the statement to be executed if the condition results in a false state.
Consider the below example:
package Edureka;public class JavaOperators {
public static void main(String[] args) {
int a = 20, b = 10, c = 30, res;
res = ((a > b) ? (a > c)? a: c: (b > c)? b: c);
System.out.println("Max of three numbers = "+ res);
}
}
Output — Max of three numbers = 30
Moving ahead to the last java operator, let’s understand Shift operators in Java.
Shift Operators in Java
Shift operators are used to shifting the bits of a number left or right, thereby multiplying or dividing the number. There are three different types of shift operators, namely left shift operator()<<, signed right operator(>>) and unsigned right shift operator(>>>).
Syntax:
numbershift_op number_of_places_to_shift;Consider the following example:
package Edureka;public class JavaOperators {
public static void main(String[] args) {
int a=58;
System.out.println(a<<2); //232=11101000
System.out.println(a>>2); //returns 14=1110
System.out.println(a>>>2); //returns 14
}
}
