Java - String equals Method - This method compares this string to the specified object. The result is true if and only if the argument is not null and is a String object that represents the. When n is equal to zero, it's going to be two plus three times zero. So that's just going to be two. And then plus, when n is equal to one, it's going to be two plus three times one, which is five. This is starting to look good. Now when n is equal to, this was n equals zero, this was n equals one, so now we're at n equals two. So, that's the number 3, so h of 3 is going to be 3 times 3 minus 1, 3 minus 1 squared, minus 5, which is equal to 3 times 2 squared, this is 2 right over here, minus 5, which is equal to 3 times 4 minus 5, which is equal to 12 minus 5, which is equal to 7. So, you input negative 6 into g, you get 3.
Comparison Operators
Comparison operators are used in logical statements to determine equality or difference between variables or values.
Given that
x = 5
, the table below explains the comparison operators:Operator | Description | Comparing | Returns | Try it |
---|---|---|---|---|
equal to | x 8 | false | Try it » | |
x 5 | true | Try it » | ||
x '5' | true | Try it » | ||
equal value and equal type | x 5 | true | Try it » | |
x '5' | false | Try it » | ||
!= | not equal | x != 8 | true | Try it » |
! | not equal value or not equal type | x ! 5 | false | Try it » |
x ! '5' | true | Try it » | ||
x ! 8 | true | Try it » | ||
> | greater than | x > 8 | false | Try it » |
< | less than | x < 8 | true | Try it » |
>= | greater than or equal to | x >= 8 | false | Try it » |
<= | less than or equal to | x <= 8 | true | Try it » |
How Can it be Used
Comparison operators can be used in conditional statements to compare values and take action depending on the result:
You will learn more about the use of conditional statements in the next chapter of this tutorial.
Logical Operators
Logical operators are used to determine the logic between variables or values.
Given that
x = 6
and y = 3
, the table below explains the logical operators: Operator | Description | Example | Try it |
---|---|---|---|
&& | and | (x < 10 && y > 1) is true | Try it » |
|| | or | (x 5 || y 5) is false | Try it » |
! | not | !(x y) is true | Try it » |
Conditional (Ternary) Operator
JavaScript also contains a conditional operator that assigns a value to a variable based on some condition.
Syntax
Example
var voteable = (age < 18) ? 'Too young':'Old enough';
Try it Yourself »If the variable age is a value below 18, the value of the variable voteable will be 'Too young', otherwise the value of voteable will be 'Old enough'.
Comparing Different Types
Gobdocuments 1 6 Equals Equal
Comparing data of different types may give unexpected results.
Gobdocuments 1 6 Equals Ounces
When comparing a string with a number, JavaScript will convert the string to a number when doing the comparison. An empty string converts to 0. A non-numeric string converts to
NaN
which is always false
.Case | Value | Try |
---|---|---|
2 < 12 | true | Try it » |
2 < '12' | true | Try it » |
2 < 'John' | false | Try it » |
2 > 'John' | false | Try it » |
2 'John' | false | Try it » |
'2' < '12' | false | Try it » |
'2' > '12' | true | Try it » |
'2' '12' | false | Try it » |

When comparing two strings, '2' will be greater than '12', because (alphabetically) 1 is less than 2.

Gobdocuments 1 6 Equals Grams
age = Number(age);
if (isNaN(age)) {
voteable = 'Input is not a number';
} else {
voteable = (age < 18) ? 'Too young' : 'Old enough';
}
Try it Yourself »if (isNaN(age)) {
voteable = 'Input is not a number';
} else {
voteable = (age < 18) ? 'Too young' : 'Old enough';
}
