use parentheses?

What do you mean, "solve" it?

What does your book say (you are using a book, right?)

Read one of my blog articles (see the link near the top-right of this reply); the article discusses a fairly complete expression parser and several evaluators (all code is included). You can also do it the lazy way and let the embedded Javascript engine do the nitty-gritty work.

kind regards,

one acronym: BODMAS

1. Brackets

2. Of

3. Divide

4. Multiplication

5. Addition

6. Subtration

Precedence indicated by the numbers - 07-12-2013, 10:12 AMgimbal2Re: How do i solve a java precedence PLEEEASE HELP ME :(
2 = Orders, not of.

@YoHeHo :

Quote:

Use the BODMAS principle

I think your equation can be re write to this form ::

**4+(3*(2/3))-(7*3)+((15/2)*(7/2))+1**

I wrote a java code for you, i also didn't understand what do you mean by the word "solve" here

Code:`import java.io.*;`

class operation

{

public static void main(String args[])

{

float a=4+(3*(2/3))-(7*3)+((15/2)*(7/2))+1;

System.out.println("Result : "+a);

}

}

The BODMAS principle doesn't apply to Java. For example, division and multiplication have the same precedence so they then evaluate from left to right in the absence of parens.

int a = 2/3*3; // evaluates to 0

int b = 3*2/3; // evaluates to 2
