Get Text and Positions from a Java jTextArea

I want to get the individual texts and their positions as they are entered in an editable jTextArea.

for example ,the following string: "this is java"

should provide the following:

word position this p1 is p2 java p3

any suggestion on how to achieve this. kind regards.

Solution

  • You can do something like this

    JTextArea textArea = new JTextArea();
textArea.setText("this is java");
StringTokenizer stringTokenizer = new StringTokenizer(textArea.getText());
int position = 1;
while(stringTokenizer.hasMoreTokens())
{
    System.out.println("Position" + position + ":" + stringTokenizer.nextToken());
}

    Output is 

    Position1:this
Position1:is
Position1:java

    However you wish to know current CaretPosition then you can do textArea.getCaretPosition();.
