Print below star pattern in Java     *    **   ***  **** ***** Here is code to do this import java.util.*; class start2Patteran{ public static void main(String [] args){ for(int i=1;i<=5;i++){ for(int j=0;j<(5-i);j++){ System.out.print(" "); } for(int k=1;k<=i;k++){ System.out.print("*"); } System.out.println(); } } }

Enter the number to show them in sequence of max 5 number in row.      for example print below number:-     1 2 3 4 5              6 7 8 9 10            11 12                 Here is Java code for to do this:-      import java.util.*;        class printNoSquesce{  public static void main(String args[]){ int i=12; StringBuilder sb=new StringBuilder(); for(int j=1;j<=i;j++){ if(j%5==0 ){ sb.append(j); sb.append(" "); sb.append("\n"); System.out.println(); }else{ sb.append(j); sb.append(" "); } } System.out.print(sb);       }      } Below in output Of programme
