Program: How to get line count from a string?

This example shows how to get line count from a string. Assuming that we have read the file and keeping the content in string. We are using String.split() method with the use of regular expression [\n|\r]. It will split the string based on the new line char and carriage return char. After the split, we will get string array, and returning length of the array.

package com.java2novice.string;

public class MyStringLineCounter {

	public static int getLineCount(String text){
		
		return text.split("[\n|\r]").length;
	}
	
	public static void main(String a[]){
	
		String str = "line1\nline2\nline3\rline4";
		System.out.println(str);
		int count = getLineCount(str);
		System.out.println("line count: "+count);
	}
}

line1
line2
line3
line4
line count: 4
