Java Basics---Java arithmetic operators (11)

Arithmetic operators in Java

Arithmetic operators are primarily used for basic arithmetic operations, such as addition, subtraction, multiplication, division, and so on.

Arithmetic operators commonly used in Java:

650) this.width=650; "src=" http://img.mukewang.com/5368a1a10001da7603050148.jpg "/>

where+ + and -- can appear either on the left side of the operand or on the right, but the result is a different drop

650) this.width=650; "src=" http://img.mukewang.com/5368a1f1000171c403980094.jpg "/>

Operation Result: 650) this.width=650; "src=" http://img.mukewang.com/535e6a9c000128ef00900039.jpg "/>

650) this.width=650; "src=" http://img.mukewang.com/5368a0ae00016f2603970091.jpg "/>

Operation Result: 650) this.width=650; "src=" http://img.mukewang.com/535e6b040001403800890034.jpg "/>

Must pay attention to Oh! The increment and decrement operators can only be used for operation variables and cannot be used directly to manipulate values or constants! For example, 5++, 8--and so on are all wrong!

ps:% is used to find the remainder, also known as the modulo operator.

Code:

public class helloworld{
public static void Main (string[] args) {
int age1=24;
int age2=18;
int age3=36;
int age4=27;
int sum=age1+age2+age3+age4;
Double AVG=SUM/4;
int minus=age1-age2;
int newage=--age1;



System.out.println ("Sum of the Ages:" +sum);
System.out.println ("average age:" +avg);
System.out.println ("Age Difference:" +minus);
System.out.println ("Age after self-reduction:" +newage);

}
}

Operation Result:

Total Age: 105
Average age: 26.0
Age Difference: 6
Age after self-reduction: 23
