Thread: pythagorean triples using a for loop

I have generated many errors in my code for this program but I particularly want to focused on the first error that comes up. Here is the outline of my code:

//a java application that prints the table of pythagorean triples that go up to 500 using a for loop
public class luby{
 
	//main method executes java application
 
	public static void main(String args[]){
 
//declare variables
 
 
 
for(int side_1=1; int side_1 <=500;  side_1++){
 
	for(int side_2=1; int side_2 <=500; side_2++){
 
		for(int hypotenuse=1; int hypotenuse <=500; hypotenuese++){
 
			Math.pow(hypotenuese,2)=Math.pow(side_1,2)+Math.pow(side_2,2);
 
			System.out.printf("n/%d/n", Math.pow(side_1,2),"                 ", Math.pow(side_2,2),"                 ", Math.pow(hypotenuse,2));
 
 
 
} //end first for loop
 
}//end second for loop
 
}
 
	 //end third for loop
 
}//end main
 
}//end class

Here is the output of my code when I attempt to compile it:

The first error I want to focus on is the class error; I will focus on the remaining errors once this error is resolved

If I try to compile this code I get very different errors. Are you sure you copied the right output?

Fixed most of my errors. Now only one error is generated when I attempt to compile the code:

//a java application that prints the table of pythagorean triples that go up to 500 using a for loop
public class luby{
 
	//main method executes java application
 
	public static void main(String args[]){
 
//declare variables
 
 
 
for(int side_1=1;  side_1 <=500;  side_1++){
 
	for(int side_2=1;  side_2 <=500; side_2++){
 
		for(int hypotenuse=1;  hypotenuse <=500; hypotenuse++){
 
			Math.pow(hypotenuse,2)=Math.pow(side_1,2)+Math.pow(side_2,2);
 
			System.out.printf("n/%d/n", Math.pow(side_1,2),"                 ", Math.pow(side_2,2),"                 ", Math.pow(hypotenuse,2));
 
}
 
}//end second for loop
 
}
 
	 //end third for loop
 
}//end main
 
}//end class

Could you try to explain to us what you are trying to do in the erroneous line?
Try to explain it step by step:

Math.pow(hypotenuse,2)=Math.pow(side_1,2)+Math.pow (side_2,2);

I want to displayed a table of pythagorean triples that until the values reach 500.The code above is supposed to be the equation for the pythagorean theorem and when I attempt to compile it, java doesn't recognize it as a statement.

Because it isnt.
You have a value on the left hand side of the assignment operator, and a value on the right hand side.

It is as if you would write "5 = 2 + 2". Its not an assignment, its not even a valid statement in java.
The assignment operator must be used with a variable on the left hand side and an expression on the right hand side.

I used double equal signs

Math.pow(hypotenuse,2)==Math.pow(side_1,2)+Math.po w(side_2,2);

and that didn't even work
