Do we have some placeholders in java for string as we have (?) in SQL prepared statement

You can use String.format

String st = "akkk %s la,ala %s "; 
String result = String.format(st, "First Val", "Second Val");

Alternatively, you can use numeric positions

String st = "akkk %1$s la,ala %2$s "; 
String result = String.format(st, "First Val", "Second Val");

you can look at this Class MessageFormat
