I want to dispaly in Hindi language in console using Java.

if i simply print like this
String str=”\u0905\u092d\u0940 \u0938\u092e\u092f \u0939\u0948 \u091c\u0928\u0924\u093e \u091c\u094b \u091a\u093e\u0939\u0924\u0940 \u0939\u0948 \u092″;

System.out.println(str);

then it works fine but when i try to read from a file it doesn’t work.

Answer 1

Use Apache Commons Lang.

import org.apache.commons.lang3.StringEscapeUtils;

// open the file as ASCII, read it into a string, then
String escapedStr; // = "\u0905\u092d\u0940 \u0938\u092e\u092f \u0939\u0948 ..."
// (to include such a string in a Java program you would have to double each \)

String hindiStr = StringEscapeUtils.unescapeJava( escapedStr );

System.out.println(hindiStr);

(Make sure your console is set up to display Hindi (correct fonts, etc) and the console’s encoding matches your Java encoding. The Java code above is just the bare bones.)
