1)class Pattern
{
void main()
{
String s = "BLUEJ"
int n = s.length();
int i, j;
for(i=0; i<n; i++)
{
for(j=0; j<=i; j++)
{
System.out.print( s.charAt(i) );
}
System.out.println();
}
}
}

2)import java.util.*
class Vowel
{
void main()
{
Scanner sn = new Sccanner (System.in);
System.out.println("Enter a string");
String s= sn.nextLine();
char ch;
int n, count =0;
n=s.length();
for(i=0; i<n; i++)
{
ch = s.charAt(i)
if ( ch=='A' || ch=='a' || ch=='E' || ch=='e' || ch=='I' || ch=='i' || ch=='O' || ch=='o' || ch=='U' || ch=='u')
{
count++;
}
}
System.out.println("Total number of vowels = " + count);
}
}

3)import java.util.*
class Replace
{
void main()
{
Scanner sn = new Scanner (System.in);
System.out.println("Enter string in lower case");
String s = sn.nextLine();
s=s.toLowerCase();
