Maari pong gawin ang desired output gamit ang nested loop sa Java. Narito po ang isang code na maaaring maging gabay:
Ang kodigo ay nagtatanim ng dalawang nested loops. Ang unang loop ay tumatakbo sa bawat row ng desired output, habang ang pangalawang loop ay magpapakita ng mga number sa bawat column. Magsisimula ang pangalawang loop sa max level ng triangle at magbabawas ng 1 sa bawat iteration. Ang output ng program ay magiging:
Maari mong baguhin ang value ng
Code:
public class RightTriangle {
public static void main(String[] args) {
int rows = 5;
int num = 16;
for (int i = 1; i <= rows; i++) {
for (int j = i; j >= 1; j--) {
num--;
System.out.print(num + " ");
}
System.out.println();
}
}

rows variable sa kagustuhan mo. Sana nakatulong po ito.
import java.util.Scanner;
import java.util.Random;
public class RandomPyramidNumbers {
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
System.out.print("Enter the number of rows: ");
int rows = scanner.nextInt();
Random rand = new Random();
for (int i = 1; i <= rows; i++) {
for (int j = 1; j <= i; j++) {
System.out.print(rand.nextInt(100) + " ");
}
System.out.println();
}
}
}
Or baka ito given random numbers using array

import java.util.Random;
import java.util.Scanner;
public class RandomTriangle {
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);

int[] numbers = new int[rows];
for (int i = 0; i < rows; i++) {
numbers = random.nextInt(100);
}
System.out.println("Random numbers: " + Arrays.toString(numbers));
System.out.println("Right triangle:");
for (int i = 0; i < rows; i++) {
for (int j = 0; j <= i; j++) {
System.out.print(numbers[j] + " ");
}

Here's a Java program that will output the pattern you provided:
This program uses nested loops to iterate through the rows and columns of the pattern. The outer loop controls the rows, while the inner loop controls the number of elements in each row.
The currentNum variable keeps track of the current number to be printed in the pattern. It starts at the last number in the pattern, which is equal to n*(n+1)/2. Each time an element is printed, currentNum is decremented by one.
At the end of each row, currentNum is updated to point to the start of the next row. The amount to add depends on the current row number i, since each row has one less element than the previous row.
Java:
public class Pattern {
public static void main(String[] args) {
int n = 5;
int currentNum = n * (n + 1) / 2;
for (int i = 0; i < n; i++) {
for (int j = 0; j <= i; j++) {
System.out.print(currentNum + " ");
currentNum--;
}
System.out.println();
currentNum += n - i + 1;
}
}

basic java program po using nested for loops without rand and arrays po

eto po output nyan
ou nga, pero ilang beses ko na tinanong chatgpt at BAI Chat pero mali2 talaga binibigay na code haha

Pag nakuha mo paps papost na lang dito. Salamat. Tinatry ko din kaso hirap tlga.
ito lang nakayanan ko,
Java:
public class Pattern {
public static void main(String[] args) {
for (int i = 5; i > 0; i--) {
int num = i;
for (int j = 1; j <= i; j++) {
System.out.print(num + " ");
num += 5 - j;
}
System.out.println();
}
}

Hindi pa din sir. Thank you for trying po
kung given na kasi yung mga needs mo na number need na ata array jan
tama naman yung output, i reverse mo lang ang orientation, but you need arrays.

Di ko alam ano trip ng prof niyo at ito ang pinagawa. Balik ka lang sa basic, dapat alam mo yung different types of sequence. So dito, arithmetic sequence lang ginamit.
Java:
import java.util.Scanner;
public class Pyramid {
public static void main(String[] args) {
Scanner in = new Scanner(System.in);
System.out.print("Enter Rows: ");
int input = in.nextInt();
int rowDiff, colDiff = input+1, numToPrint = input, lastNum = input;
for (int i=1; i<=input; i++){
rowDiff = input - i;
for (int j=1; j<=i; j++){
System.out.print(numToPrint + " ");
numToPrint = numToPrint - (colDiff + j - 1);
}
numToPrint = lastNum + rowDiff;
lastNum = numToPrint;
colDiff--;
System.out.println();
}
}

Tama na tong ginawa paps pero ibahin ko structure para di na need mag input ng rows.
Java:
public class pyramid {
public static void main(String[] args) {
final int NUM_ROWS = 5;
int rowDiff, colDiff = NUM_ROWS+1, numToPrint = NUM_ROWS, lastNum = NUM_ROWS;
for (int i=1; i<=NUM_ROWS; i++){
rowDiff = NUM_ROWS - i;
for (int j=1; j<=i; j++){
System.out.print(numToPrint + " ");
numToPrint = numToPrint - (colDiff + j - 1);
}
numToPrint = lastNum + rowDiff;
lastNum = numToPrint;
colDiff--;
System.out.println();
}
}

Bawal pa po arrays.
Galing. Thank you po
Salamat din po sa pag ayos

Pero feeling ko need niya yung may input. kadalasan sa mga ganiyang activity, need talaga mag-input ng rows. Lalo na't pyramid yan
galing ng logic nito. ilang years kanang dev?
mas magaling po ako HAHAHA tingnan mo tong code Schiro simple lng at basic
Java:
public class Main
{
public static void main(String[] args) {
System.out.println("5\n9 4\n12 8 3\n14 11 7 2\n15 13 10 6 1");
}
