PAGE-2 : NUMBER PATTERN PROGRAMS

Print Patterns Of Number

Same as Star Pattern , you can print number patterns too.

Explanation of Code

Scanner s=new Scanner(System.in): are used for receive input from keyboard.

nextInt(): method are used for get integer type value from keyboard.

System.out.println("....."): are used for display message on screen or console.

System.out.print("....."): are used for display message on screen or console but cursor not move in new line.

System.out.println("....."): are used for display message on screen or console cursor move in new line.

Pattern-1 :

package com.numberpattern;

import java.io.BufferedReader;

import java.io.InputStreamReader;

public class NumberPatternProgram1 {

public static void main(String[] args) {

InputStreamReader istream = new InputStreamReader(System.in);

BufferedReader read = new BufferedReader(istream);

System.out.print("Enter Pattern Size : ");

int num = 0;

try {

num = Integer.parseInt(read.readLine());

} catch (Exception Number) {

System.out.println("Invalid Number!");

}

for (int i = 1; i <= num; i++) {

for (int j = 1; j <= i; j++) {

System.out.print(j);

}

System.out.println();

}

}

}

OUTPUT : 

Enter Pattern Size : 5

Pattern-2 :

package com.numberpattern;

import java.io.BufferedReader;

import java.io.InputStreamReader;

public class NumberPatternProgram2 {

public static void main(String[] args) {

InputStreamReader istream = new InputStreamReader(System.in);

BufferedReader read = new BufferedReader(istream);

System.out.print("Enter Pattern Size : ");

int num = 0;

try {

num = Integer.parseInt(read.readLine());

} catch (Exception Number) {

System.out.println("Invalid Number!");

}

for (int i = 1; i <= num; i++) {

for (int j = 5; j >= i; j--) {

System.out.print(j);

}

System.out.println();

}

}

}

OUTPUT : 

Enter Pattern Size : 5

Pattern-3 :

package com.numberpattern;

import java.io.BufferedReader;

import java.io.InputStreamReader;

public class NumberPatternProgram3 {

public static void main(String[] args) {

InputStreamReader istream = new InputStreamReader(System.in);

BufferedReader read = new BufferedReader(istream);

System.out.print("Enter Pattern Size : ");

int num = 0;

try {

num = Integer.parseInt(read.readLine());

} catch (Exception Number) {

System.out.println("Invalid Number!");

}

for (int i = 1, r = num; i <= num; i++, r--) {

for (int j = 1; j <= r; j++) {

System.out.print(j);

}

System.out.println();

}

}

}

OUTPUT : 

Enter Pattern Size : 5

PATTERN-4 :

package com.numberpattern;

import java.io.BufferedReader;
import java.io.InputStreamReader;

public class NumberPatternProgram4 {
public static void main(String[] args) {
InputStreamReader istream = new InputStreamReader(System.in);
BufferedReader read = new BufferedReader(istream);
System.out.print("Enter Pattern Size : ");
int num = 0;
try {
num = Integer.parseInt(read.readLine());
} catch (Exception Number) {
System.out.println("Invalid Number!");
}

for (int j = 0; j < num; j++) {
for (int i = 0; i <= (num - j); i++) {
System.out.print(" ");
}
for (int count = 0; count < (2 * j + 1); count++)
System.out.print(j + 1);
System.out.println();

}

}

}

OUTPUT : 

Enter Pattern Size : 5
