Thread: Replacing File Content

Hi All,

I had written a piece of code previosly

String uniqueFormula = tempFormula[0];
String[] tempMapVars = tempFormula[1].split("\\s*;\\s*");
System.out.println(tempMapVars.length);
	for (int i=0; i< tempMapVars.length; i++){
		String[] keyValue = tempMapVars[i].split("\\s*=\\s*",2);
		      if (keyValue.length==2){
			StringBuffer sb = new StringBuffer(keyValue[0]);
			sb.append("_").append(runNo++);
			uniqueFormula = uniqueFormula.replace(keyValue[0],sb.toString());	
		             var2MeasParaHM.put(new String(sb.toString()), new String(keyValue[1]));
		      }
                 }

The content of Unique Formula is as given below initially.

(if(V1>2.0E-8&&V1<2.0E-7&&V2>2.0E-8&&V2<2.0E-7&&V3>2.0E-8&&V3<2.0E-7&&V4>2.0E-8&&V4<2.0E-7&&V5>2.0E-8&&V5<2.0E-7&&V6>2.0E-8&&V6<2.0E-7&&V7>2.0E-8&&V7<2.0E-7&&V8>2.0E-8&&V8<2.0E-7&&V9>2.0E-8&&V9<2.0E-7&&V10>2.0E-8&&V10<2.0E-7,output=1.0,output=0.0))*1

The idea behind code is to append a unique number along with v1,v2,v3 and so on to make it unique.
so after running the piece of code the UniqyeFormula Becomes like this

(if(V1_0>2.0E-8&&V1_0<2.0E-7&&V2_1>2.0E-8&&V2_1<2.0E-7&&V3_2>2.0E-8&&V3_2<2.0E-7&&V4_3>2.0E-8&&V4_3<2.0E-7&&V5_4>2.0E-8&&V5_4<2.0E-7&&V6_5>2.0E-8&&V6_5<2.0E-7&&V7_6>2.0E-8&&V7_6<2.0E-7&&V8_7>2.0E-8&&V8_7<2.0E-7&&V9_8>2.0E-8&&V9_8<2.0E-7&&V1_00>2.0E-8&&V1_00<2.0E-7,output=1.0,output=0.0))*1

The issue i face in when Parameter becomes in Double Digit. V1 becomes V1_0 which is correct But V10 Becomes V1_00 which is not correct.

uniqueFormula = uniqueFormula.replace(keyValue[0],sb.toString());

This piece of line V1 with V1_0.....but its also searching for V10 and splits it as V1_00.

Can anyone Suggest how to overcome this issue.

Hi,

Any suggestion using RegEx?

Any suggestion guys?

This made it work perfect.

uniqueFormula = uniqueFormula.replaceAll("\\b"+keyValue[0]+"\\b",sb.toString());
