Java Basics---Comparison operators in Java (13)

comparison operators in Java

The comparison operator is used to determine the size of two data, for example: greater than, equal to, not equal to. The result of the comparison is a Boolean value (True or false).

The common comparison operators in Java are shown in the following table:

Attention, OH:

1, >, <, >=, <= only support the left and right sides of the operand is a numeric type

2, = =,! = The operands on either side of the number can be numeric types, or they can be reference types

Code:

public class helloworld{
public static void Main (string[] args) {
int a=16;
Double b=9.5;
String str1= "Hello";
String str2= "IMOOC";
System.out.println ("A equals B:" + (a== b));
SYSTEM.OUT.PRINTLN ("A greater than B:" + (a> b));
System.out.println ("A is less than or equal to B:" + (A < b));
System.out.println ("str1 equals str2:" + (str1 = str2));
}
}

Operation Result:

A equals B:false.
A greater than b:true
A is less than or equal to B:false
Str1 equals Str2:imooc.
