This article mainly explains "what are the arithmetic operators of java and how to use them". The content of the explanation in the article is simple and clear, and it is easy to learn and understand. Please follow Xiaobian's train of thought to study and learn "what are the arithmetic operators of java and how to use them?"

Arithmetic operator

Arithmetic operators are used in mathematical expressions, and they play the same role as in mathematics. The following table lists all the arithmetic operators.

The example in the table assumes that the value of integer variable An is 10 and that of variable B is 20:

Operator description + addition-values on both sides of the addition operator-subtraction-left Operand minus right Operand * value / Division-left Operand divided by right Operand% remainder-left Operand divided by the remainder of the right Operand + + self-increment: the value of the Operand increases by 1-- self-subtraction: the value of the Operand decreases 1 example public static void main (String [] args) {int a = 10 Int b = 20; int c = 25; int d = 25; System.out.println ("a + b =" + (a + b)); System.out.println ("a-b =" + (a-b)); System.out.println ("a * b =" + (a * b)); System.out.println ("b / a =" + (b / a) System.out.println ("b% a =" + (b% a)); System.out.println ("c% a =" + (c% a)); System.out.println ("aqu + =" + (aqu +)); System.out.println ("aMub-=" + (Amura -)); / / View the different System.out.println of dumped + and + + d ("dashed + =" + (dumped +)) System.out.println ("+ d =" + (+ d)) } run result "C:\ Program Files\ Java\ jdk1.8.0_192\ bin\ java.exe"-javaagent:C:\ Program Files\ JetBrains\ IntelliJ IDEA 2020.1.3\ lib\ idea_rt.jar=51196:C:\ Program Files\ JetBrains\ IntelliJ IDEA 2020.1.3\ bin "- Dfile.encoding=UTF-8-classpath" C:\ Program Files\ Java\ jdk1.8.0_192\ jre\ lib\ charsets.jar C:\ Program Files\ Java\ jdk1.8.0_192\ jre\ lib\ deploy.jar;C:\ Program Files\ Java\ jdk1.8.0_192\ jre\ lib\ ext\ access-bridge-64.jar;C:\ Program Files\ Java\ jdk1.8.0_192\ jre\ lib\ ext\ cldrdata.jar;C:\ Program Files\ Java\ jdk1.8.0_192\ jre\ lib\ ext\ dnsns.jar;C:\ Program Files\ Java\ jdk1.8.0_192\ jre\ lib\ ext\ jaccess.jar C:\ Program Files\ Java\ jdk1.8.0_192\ jre\ lib\ ext\ jfxrt.jar;C:\ Program Files\ Java\ jdk1.8.0_192\ jre\ lib\ ext\ localedata.jar;C:\ Program Files\ Java\ jdk1.8.0_192\ jre\ lib\ ext\ nashorn.jar;C:\ Program Files\ Java\ jdk1.8.0_192\ jre\ lib\ ext\ sunec.jar;C:\ Program Files\ Java\ jdk1.8.0_192\ jre\ lib\ ext\ sunjce_provider.jar C:\ Program Files\ Java\ jdk1.8.0_192\ jre\ lib\ ext\ sunmscapi.jar;C:\ Program Files\ Java\ jdk1.8.0_192\ jre\ lib\ ext\ sunpkcs11.jar;C:\ Program Files\ Java\ jdk1.8.0_192\ jre\ lib\ ext\ zipfs.jar;C:\ Program Files\ Java\ jdk1.8.0_192\ jre\ lib\ javaws.jar;C:\ Program Files\ Java\ jdk1.8.0_192\ jre\ lib\ jce.jar C:\ Program Files\ Java\ jdk1.8.0_192\ jre\ lib\ jfr.jar;C:\ Program Files\ Java\ jdk1.8.0_192\ jre\ lib\ jfxswt.jar;C:\ Program Files\ Java\ jdk1.8.0_192\ jre\ lib\ jsse.jar;C:\ Program Files\ Java\ jdk1.8.0_192\ jre\ lib\ management-agent.jar;C:\ Program Files\ Java\ jdk1.8.0_192\ jre\ lib\ plugin.jar C:\ Program Files\ Java\ jdk1.8.0_192\ jre\ lib\ resources.jar;C:\ Program Files\ Java\ jdk1.8.0_192\ jre\ lib\ rt.jar D:\ JavaProject\ 20210402\ out\ production\ 20210402 "Testa + b = 30a-b =-10a * b = 200b / a = 2b% a = 0c% a = 5a * + = 10a Testa-= 11dink + = 25roomd = 27Process finished with exit code 0 relational operator description = = check if the values of the two operands are equal, if the conditions are true.! = check whether the values of the two operands are equal, and the condition is true if the values are not equal. > check whether the value of the left Operand is greater than that of the right Operand.
