Question

I am having trouble getting my program to run. I am getting the error message: "..\Playground"\:2: error: '{' expected
public class Program
^
1 error"

I am not sure what to change. Any ideas?

public class Program

import java.math.*
{

public static void main(String[] args) {

//variables
int x = 1;
int y = 1;
int z;
int zArray[];
int zNext = 0;
boolean inZArray = false;

// Loop through x values 1 - 100
for(x=x;x<101;x++){

// We need to start process before we check while condition
do {
// Check if z has a decimal
if (sqrt(x^2+y^2)%1 == 0){
// If not, change value to int
z = (int)z;

// Loop through list of correct z values
for(int i: zArray){
// If a value of z already exists here
if (i == z){
// Set inZArray to true
inZArray = true;
}
}
// If z is NOT already in zArray
if (inZArray == false){
// Add z to array
zArray[zNext] = z;
// Increase zNext by one to make next z placed 1 index up
zNext++;
}
// Set inZArray back to false
inZarray = false;
}
// Increase y value by one
y++;
} while(y<101);

// Set y back to 1 before x increases by one
y = 1;
}
}
}

Answer 1

switch the `import ...` with `public class ...`.

The error message is telling you that there is something wrong with your class declaration.

Answer 2

place public class Program below the import statement.

import java.math.*

public class Program {
//content
}
