I have a very simple java program to prompt user input for certain data on console.

BufferedReader br = new BufferedReader( new InputStreamReader( System.in ));

System.out.printf( "Please enter data 1:" );
data1 =Double.parseDouble( br.readLine());

System.out.printf( "Please enter data 2:" );
data2 =Double.parseDouble( br.readLine());

The problem is when displaying the 2nd prompt, the input cursor moves to the begining of that line. Is there way to control it to move it to the end of the 2nd prompt?

Maybe you want something like this. The "\n" is the code for a line break.
		BufferedReader br = new BufferedReader( new InputStreamReader( System.in ));
 
		System.out.printf( "Please enter data 1:\n" );
		double data1 =Double.parseDouble( br.readLine());
 
		System.out.printf( "Please enter data 2:\n" );
		double data2 =Double.parseDouble( br.readLine());

You should be OK with that, but using printf without arguments is redundant. You'd be better off with simply
BufferedReader br = new BufferedReader( new InputStreamReader( System.in ));
 
System.out.print( "Please enter data 1:" );
data1 =Double.parseDouble( br.readLine());
 
System.out.print( "Please enter data 2:" );
data2 =Double.parseDouble( br.readLine());

the "\n" here will not solve the problem! it's something like "println", say that "the input value will be at the next line".
But the problem here, The cursor is at the beginning of 2nd line after typing Enter at the 1st line => How to place the cursor at the end of lines (in Eclipse)!

How was this question solved? even the author said it was ok. this site is weird.
