Today we gonna see some pattern programs.
In this program we print three row and three column.
package Pattern;
public class Pattern {
public static void main(String[] args) {
// TODO Auto-generated method stub
for (int no=1;no<=3;no++) {
for (int col=1;col<=3;col++) {
System.out.print(no);
}
System.out.println();
}
}
}
Result:
111
222
333
In this program we print letter A.
package Pattern;
public class PatternA {
public static void main(String[] args) {
// TODO Auto-generated method stub
for(int r=1;r<=5;r++) {
for(int c=1;c<=5;c++) {
if((r==1)&&((c==1)||(c==2)||(c==4)||(c==5)))
{
System.out.print(” “);
}
else if((r==2)&&((c==1)||(c==3)||(c==5)))
{
System.out.print(” “);
}
else if(((r==4)||(r==5))&&((c==2)||(c==3)||(c==4)))
{
System.out.print(” “);
}
else {
System.out.print(“*”);
}
}
System.out.println();
}
}
}
In this program we print D
package Pattern;
public class PatternD {
public static void main(String[] args) {
// TODO Auto-generated method stub
for (int row=1;row<=5;row++) {
for(int col=1;col<=3;col++) {
if((col==2 )&&((row==2)||(row==3)||(row==4))) {
System.out.print(” “);
}
else if((col==3)&&((row==1)||(row==5))){
System.out.print(” “);
}
else {
System.out.print(“*”);
}
}
System.out.println();
}
}
}
Result:
In this program we print E
package Pattern;
public class PatternE {
public static void main(String[] args) {
// TODO Auto-generated method stub
for(int r=1;r<=5;r++) {
for(int c=1;c<=3;c++) {
if(((r==2)||(r==4))&&((c==2)||(c==3))) {
System.out.print(” “);
}
else {
System.out.print(“*”);
}
}
System.out.println();
}
}
}
In this program we print Q
package Pattern;
public class PatternQ {
public static void main(String[] args) {
// TODO Auto-generated method stub
for (int r=1;r<=6;r++)
{
for(int c=1;c<=5;c++) {
if(((r==1)||(r==5))&&((c==1)||(c==5))) {
System.out.print(” “);
}
else if(((r==2)||(r==3))&&((c==2)||(c==3)||(c==4))) {
System.out.print(” “);
}
else if((r==4)&&((c==2)||(c==4))) {
System.out.print(” “);
}
else if((r==6)&&((c==1)||(c==2)||(c==3)||(c==4))){
System.out.print(” “);
}
else {
System.out.print(“*”);
}
}
System.out.println();
}
}
}
