Precedence of operators in Java

The so-called priority is the order of operations in an expression. The precedence of operators commonly used in Java is shown in the following table:

650) this.width=650; "src=" http://img.mukewang.com/5360ffb90001b4f002620224.jpg "/>

Level 1 has the highest priority, and level 11 has the lowest priority . For example, the result of x = 7 + 3 * 2 is 13 "Multiply First and add"!

PS: We don't have to go. The order of precedence of the rote operators, which is typically used to assist in priority management in real-world development. For example:

650) this.width=650; "src=" http://img.mukewang.com/5361000a000129a005060071.jpg "/>

Analysis: Parentheses have the highest precedence, so

1, execute a + 18, the result is 30

2, perform (A + 18)% 4 modulo, the result is 2

3, execute A * ((A + 18)% 4), the result is 24

Code:

public class HelloWorld {
public static void Main (string[] args) {
int m = 5;
int n = 7;
int x= (m*8/(n+2))%m;
System.out.println ("M:" + M);
System.out.println ("N:" + N);
System.out.println ("x:" + x);
}
}

Operation Result:

M:5
N:7
X:4
