textAnalyser help

[salim]

Hello,

I am totally new to Java programming and I have this problem to solve... Can anyone help me continue it or at least writing some methods for the code

it is a text analyser programm to analyse any imported text ( such as calculating the number of chars in the text, the frequency of a char .... etc)

the code is

public class textAnalyser{

String corpusID;



public textAnalyser(String corpusID){
this.corpusID = corpusID;

}
private int numChars(){

}

public String getCorpusID(){
return corpusID;
}

public int getNumChars(){
return numChars;
}
public void addTexttoCorpus(String text){

}
public void clear(){

}
public int frequencyOf(char c){

}
public double percentageOf(char c){

}
public char mostFrequent(){

}


}

Can you explain where you are having problems?
Do you have any code that will compile and execute? What you posted looks like a very bare skeleton.

Most of the code you needed is in the String API. Just check the documentation. You wont benefit anything from asking people to do the coding for you. The code u needed is just simple, with patient i know you can do it. Gudluck. =)

Should get you started.

public class TextAnalyser {
 
	private String inputString;
 
	public TextAnalyser(String inputString) {
		this.inputString = inputString;
	}
 
	public int numChars(){
		return inputString.length();	
	}
 
	public String getInputString() {
		return inputString;
	}
 
	public void addTextToInputString(String text) {
		inputString += text; //prefer string builder
	}
 
	public void clear() {
		inputString = null;
	}
 
	public int frequencyOf(char c) {
		int count = 0;
		for(int x = 0; x < inputString.length(); x++) {
			if(inputString.charAt(x) == c) {
				count++;
			}
		}
		return count;
	}
 
	public double percentageOf(char c) {
		return ((double)frequencyOf(c) / (double)inputString.length()) * 100D;
	}
 
	//public char mostFrequent(){	
	//}
 
 
}

I haven't added any null checks ect but i hope this helps.
