Java Program to Print Negative Array Numbers

Write a Java Program to Print Negative Array Numbers with an example. Or how to write a Java Program to find and return the negative items in a given array. In this count negative array numbers example, we used while loop to iterate count_NegArr array and count negative items (a number less than zero), and prints the same.

package ArrayPrograms;

public class NegativeArrayItems {
	
	public static void main(String[] args) {
		int j = 0;
		int[] Neg_arr = {-40, 15, -4, 11, -8, -13, 22, 16, -11, -99, 55, 18, -60};
		
		
		System.out.print("\nList of Negative Numbers in NEG Array : ");
		while(j < Neg_arr.length) 
		{
			if(Neg_arr[j] < 0) {
				System.out.format("%d ", Neg_arr[j]);
			}
			j++;
		}
	}
}

The Negative Array Numbers using a while loop output

List of Negative Numbers in NEG Array : -40 -4 -8 -13 -11 -99 -60 

Java Program to Print Negative Array Numbers using For Loop

This Java negative array item example allows the user to enter the Neg_arr array size and items.

package ArrayPrograms;

import java.util.Scanner;

public class NegativeArrayItems1 {
	private static Scanner sc;
	
	public static void main(String[] args) {
		int Size, i;	
		sc = new Scanner(System.in);
		
		System.out.print("\nPlease Enter the NEG Array size  : ");
		Size = sc.nextInt();
		int[] Neg_arr = new int[Size];
		
		System.out.format("\nEnter NEG Array %d elements : ", Size);
		for(i = 0; i < Size; i++) 
		{
			Neg_arr[i] = sc.nextInt();
		}
		
		System.out.print("\nList of Negative Numbers in NEG Array : ");
		for(i = 0; i < Size; i++) 
		{
			if(Neg_arr[i] < 0) {
				System.out.format("%d  ", Neg_arr[i]);
			}
		}
	}
}

In this negative array item example, we created a separate function NegativeElement to print the negative array items in the given array.

package ArrayPrograms;

import java.util.Scanner;

public class NegativeArrayItems2 {
	private static Scanner sc;
	
	public static void main(String[] args) {
		int Size, i;	
		sc = new Scanner(System.in);
		
		System.out.print("\nPlease Enter the NEG Array size  : ");
		Size = sc.nextInt();
		int[] Neg_arr = new int[Size];
		
		System.out.format("\nEnter NEG Array %d elements : ", Size);
		for(i = 0; i < Size; i++) 
		{
			Neg_arr[i] = sc.nextInt();
		}
		
		NegativeElement(Neg_arr, Size);
		
	}
	public static void NegativeElement(int[] Neg_arr, int size ) {
		int i;
		
		System.out.print("\nList of Negative Numbers in NEG Array : ");
		for(i = 0; i < size; i++) 
		{
			if(Neg_arr[i] < 0) {
				System.out.format("%d  ", Neg_arr[i]);
			}
		}
	}
}

The Negative Array Items using For Loop and functions output.

Please Enter the NEG Array size  : 9

Enter NEG Array 9 elements : -1 5 0 11 -2 -3 99 3 -5
