In programming and mathematics, the symbol "<" is used to represent the less than operator. It is a binary operator, which means that it takes two operands, and it returns a Boolean value (true or false). The less than operator compares the values of its two operands, and it returns true if the first operand is less than the second operand. Otherwise, it returns false.
The less than operator is often used to compare numbers. For example, the following code compares the values of the variables x and y, and it prints the result to the console:
int x = 5; int y = 10; if (x < y) { System.out.println("x is less than y"); } The output of this code is "x is less than y", because the value of x is less than the value of y. The less than operator can also be used to compare strings. For example, the following code compares the values of the variables str1 and str2, and it prints the result to the console:
String str1 ="Hello"; String str2 ="World"; if (str1 < str2) { System.out.println("str1 is less than str2"); } The output of this code is "str1 is less than str2", because the value of str1 comes before the value of str2 in alphabetical order. The less than operator is a versatile operator that can be used to compare a wide variety of data types. It is an essential operator for any programmer to know.

The less than operator is a versatile operator that can be used to compare a wide variety of data types. It is an essential operator for any programmer to know.
1. Binary operator
The less than operator (<) is a binary operator, which means that it takes two operands and returns a single value. The operands can be of any type, but they must be of the same type. The less than operator returns true if the first operand is less than the second operand, and false otherwise.
The less than operator is often used to compare numbers. For example, the following code compares the values of the variables x and y, and it prints the result to the console:
int x = 5; int y = 10; if (x < y) { System.out.println("x is less than y"); } The output of this code is "x is less than y", because the value of x is less than the value of y.
The less than operator can also be used to compare strings. For example, the following code compares the values of the variables str1 and str2, and it prints the result to the console:
String str1 ="Hello"; String str2 ="World"; if (str1 < str2) { System.out.println("str1 is less than str2"); } The output of this code is "str1 is less than str2", because the value of str1 comes before the value of str2 in alphabetical order.
The less than operator is a versatile operator that can be used to compare a wide variety of data types. It is an essential operator for any programmer to know.
2. Compares two operands
The less than operator (<) is a binary operator, which means that it takes two operands and returns a single value. Specifically, the less than operator compares the values of its two operands and returns true if the first operand is less than the second operand, and false otherwise.
- Operand Types
The operands of the less than operator can be of any type, but they must be of the same type. This means that you cannot compare a number to a string, or a string to a boolean. - Numeric operands
The less than operator is commonly used to compare numbers. For example, the following code compares the values of the variables x and y, and it prints the result to the console:int x = 5; int y = 10; if (x < y) { System.out.println("x is less than y"); }The output of this code is "x is less than y", because the value of x is less than the value of y. - String operands
The less than operator can also be used to compare strings. For example, the following code compares the values of the variables str1 and str2, and it prints the result to the console:String str1 ="Hello";String str2 ="World";if (str1 < str2) { System.out.println("str1 is less than str2");}The output of this code is "str1 is less than str2", because the value of str1 comes before the value of str2 in alphabetical order. - Other operand types
The less than operator can also be used to compare other types of operands, such as dates, times, and objects. The specific behavior of the less than operator depends on the type of operands being compared.
The less than operator is a versatile operator that can be used to compare a wide variety of data types. It is an essential operator for any programmer to know.
3. Returns a Boolean value
In computer programming, a Boolean value is a data type that can have only two possible values: true or false. The less than operator (<) is a binary operator that compares the values of its two operands and returns a Boolean value. Specifically, the less than operator returns true if the first operand is less than the second operand, and false otherwise.
- Facet 1: True or False

5. Can be used to compare strings
The less than operator (<) is a versatile operator that can be used to compare a wide variety of data types, including strings. This is a powerful feature that can be used for a variety of tasks, such as sorting data, searching for data, and making decisions.
When comparing strings, the less than operator compares the Unicode code points of the characters in the strings. The string with the lower Unicode code point is considered to be less than the string with the higher Unicode code point. This means that the less than operator can be used to sort strings in alphabetical order.
For example, the following code compares the values of the variables str1 and str2, and it prints the result to the console:
String str1 ="Hello";String str2 ="World";if (str1 < str2) { System.out.println("str1 is less than str2");}The output of this code is "str1 is less than str2", because the Unicode code point of the first character in str1 is less than the Unicode code point of the first character in str2.
