数字总和模式java

Question

Hello I need to create this pattern in java

Im new to this and Im trying different codes but cant find out how to do it.Ive tried this one

 public class JavaProgram
 {
 public static void main(String args[])
  {
    int i, j, num;
    for(i=1; i<=5; i++)
    {
        num=1;
        for(j=1; j<=i; j++)
        {
            System.out.print(num+ " ");
            num++;
        }
        System.out.println();
    }
}}

But the result of this one is

Any help?

Answer 1

This solution you'll find quite easier than other answers here :)

import java.util.Scanner;
public class Main {

    public static void main(String[] args) {
        // Write your code here
        Scanner s = new Scanner(System.in);
        int N = s.nextInt();
        int sum=0;
        for(int i=1;i<=N;i++){
            sum=0;
            for(int j=1;j<=i;j++){
                sum=sum+j;
                System.out.print(j);
                if(j<i)
                    System.out.print("+");
            }System.out.println("=" + sum);
        }
    }
}

Answer 2

Ok so after a few tries I found the correct code by myself. This is the solution.

public class JavaProgram
   {
    public static void main(String args[])
     {
    int i, j, num;
    for(i=1; i<=5; i++)
    {
        num=1;
        int sum=0;
        for(j=1; j<=i; j++)
        {

            System.out.print(num+ "");

            sum=sum+num;
            if (num<i) {
                System.out.print("+");
            }  
            num++;

        }

            System.out.print("="+sum);
        System.out.println();
    }
   }
}

public class Test
{
    public static void printStars(int n)
    {
        int i, j,temp = 0;

        for(i=0; i<n; i++)
        {
            for(j=1; j<=i; j++)
            {
                System.out.print(j + " ");

            }
            temp = temp + j - 1;
            if (temp>1) {
                System.out.print(temp + " ");
            }

            System.out.println();

        }
    }
    public static void main(String args[])
    {
        int n = 10;
        printStars(n);
    }

}

Using While loops

public static void main(String[] args) {

        Scanner sc = new Scanner (System.in);

        int n = sc.nextInt();

        int row = 1;

        while(n>=row){

            int col = 1;
            int sum = 0;

            while (col<=row){

                sum += col;

                System.out.print(col);

                if(row>col)
                    System.out.print(" + ");

                col++;

                }
            System.out.println(" = " + sum);
            row++;

            }
