By 'textpane' do you mean JTextPane?

StringBuilder doesn't know anything about colours. StyledDocument does, and that's what's being used by JTextPane. Just check out the methods that take an AttributeSet.

my program is to append the nos converted to string each time from the for loop so for appending i am using string builder and then converting to string and setting to JTextPane.

my problem is when i am searching one no in the entered JTextPane. that no should appear in color..i am getting that no.. but i am not knowing how to color it ... please help me sir...i need to submit this assignment as soon as possible

Check out javax.swing.text.Highlighter.

if(flag){
 if(currentValueLat == getLatSearch()){
            		   if(Val1.equalsIgnoreCase(Val2)){
            			   
            			
           			     appendColor(Color.blue, Val2);  
            			  
            			 sb.append("     " + Val2+ "        ");   

            			}

here in my GUI by clicking on the search button flag becomes true and it checks the if condition in that "currentValueLat" will come from for loop and "getLatSearch()" will be from the user (search value)

and here i need to color that value and sb is the string builder object . appendcolor is a function and i will the code for that

public void appendColor(Color c, String s) { // better implementation--uses
	        // StyleContext
	 StyleContext sc = StyleContext.getDefaultStyleContext();
	 AttributeSet aset = sc.addAttribute(SimpleAttributeSet.EMPTY,
	 StyleConstants.Foreground, c);
	
	   int len = textpane.getDocument().getLength(); // same value as// getText().length();
	  textpane.setCaretPosition(len);     // place caret at the end (with no selection)
	  textpane.setCharacterAttributes(aset, false);
	  textpane.replaceSelection(s);   // there is no selection, so inserts at caret
	  
	}

so how to do this i am a beginner for Java... so please help me ... thank you all in advance
