Thread: How to find where the biggest number is in an array

Hi i've been trying to figure out where to find the biggest number in an array. I know how to find the biggest number but i need to find out where the biggest number is, like which row or whatever it's in.

import java.util.Scanner;
public class array {
 
	public static void main (String args[]) {
 
	Scanner keyboard = new Scanner(System.in);
 
	int r[] = new int[50];
	int n=0;
	int x, bigSoFar;
 
	System.out.print("Enter list: ");
	x = keyboard.nextInt();
 
	while( x!= -999); {
		r[n] = x;
		n++;
		x = keyboard.nextInt();
	}
 
	for(int k = 0; k < n; k++)
		if(r[k]> bigSoFar) {
 
			bigSoFar = r[k]; 
		}	
 
		System.out.println(r[k]); 
 
	}	
}

Although first i'm having trouble trying to get my first code to work, i keep getting this error
array.java:34: error: cannot find symbol
System.out.println(r[k]);
^
symbol: variable k
location: class array
1 error

Check the { }
It seems the compiler believes k is not defined within scope every time it is being used.
Look at line 34's use of k

k is defined as k=0 inside the parenthesis and as for the braces, where else could i place them?

Check the positioning of the { } again. For some reason the scope of the for loop does not include k on line 34.

class ForDemo {
    public static void main(String[] args){
         for(int i=1; i<11; i++){
              System.out.println("Count is: " + i);
         }
         for(int i=1; i<11; i++)
         System.out.println("Count is: " + i);
         System.out.println("I am outside the loop);
    }
}

If the for loop is not followed by a curly brace, but instead followed by a statement ending with a semicolon, the scope of the for loop terminates at the semicolon. Demonstrated by the class above, a modified version from the java for loop tutorial

ok I fixed it and I was able to compile it but now whenever i try to put a list in in the command prompt it will just sit there and not do anything, just freeze and think. I can't figure it out

import java.util.Scanner;
 
public class array {
 
	public static void main (String args[]) {
 
	Scanner keyboard = new Scanner(System.in);
 
	int r[] = new int[50];
	int n=0;
	int x, bigSoFar=0;
 
	System.out.print("Enter list: ");
	x = keyboard.nextInt();
 
	while( x!= -999); {
 
		r[n] = x;
		n++;
		x = keyboard.nextInt();
 
	}
 
	for(int k = 0; k < n; k++){
		if(r[k] > bigSoFar) {
 
			bigSoFar = r[k]; 
		}	
 
		System.out.println(r[k]); 
		}
 
	}
 
 
}
