Question

I need to get the unique name from a string and concatenate with an integer in java.So I want to take first letter of the string and increment that letter with an integer.
Example: tenant name:
“ani,raj,rob” and i need to get the
schema name like a001,r001,r002
here r value will be incremented because of repetition.So I request you to help me find answer for this.I am getting the first letter from a string but I need to concatenate that with an integer.

String name = new String(tenantName); 
char sc=tenantName.charAt(0); 
String whereClause="tenant_id= select max(tenant_id) from tenant_connection_details 
                                        tcd1 where schema_name like'"+sc+"%'"; 
tenantList= tenantImpl.getAllTenantsByWhereClause(whereClause); 

Answer 1

List<String> myNames = new ArrayList<String>();
myNames.add("ani");
myNames.add("raj");
myNames.add("rob");
myNames.add("jigar");

int counter=1;
for(String str:myNames){
System.out.println(str.charAt(0)+String.format("%04d", i));
counter++;
}
