How to compare two String objects in java?


Description:

The below example shows how to compare two string objects in java. You can not use "==" operator to compare two strings. String provides equals() method to compare two string objects. Also you can ignore case during string compare by calling equalsIgnoreCase() method. '==' operator compares the object reference but not the string value.


Code:
package com.myjava.string;

public class MyStringEquals {
    public static void main(String a[]){
        String x = "JUNK";
        String y = "junk";
        /**
         * We cannot use '==' operator to compare two strings.
         * We have to use equals() method.
         */
        if(x.equals(y)){
            System.out.println("Both strings are equal.");
        } else {
            System.out.println("Both strings are not equal.");
        }
        /**
         * We can ignore case with equalsIgnoreCase() method
         */
        if(x.equalsIgnoreCase(y)){
            System.out.println("Both strings are equal.");
        } else {
            System.out.println("Both strings are not equal.");
        }
    }
}

Example Output

Both strings are not equal.
Both strings are equal.

ServletOuptputStream Vs PrintWriter
ServletOutputStream: ServletResponse.getOutputStream() returns a ServletOutputStream suitable for writing binary data in the response. The servlet container does not encode the binary data, it sends the raw data as it is.

PrintWriter: ServletResponse.getWriter() returns PrintWriter object which sends character text to the client. The PrintWriter uses the character encoding returned by getCharacterEncoding(). If the response's character encoding has not been specified then it does default character encoding.
