Here, we have two strings str1 and str2, str2 will be replaced with str1 and finally, str1 is the replaced string (which will be returned through the function).
//Java Program to replace a string with new one.
public class JavaStringReplacePrg
{
public static void main(String args[])
{
//string 1
String str1="www.includehelp.com";
//string 2
String str2="Hello World!";
//printing strings before replacing
System.out.println("\nStrings before replacing:");
System.out.println("str1: "+str1 +"\nstr2:" + str2);
//replacing string str1 with str2
str1=str1.replace(str1, str2);
//printing strings after replacing
System.out.println("\nStrings after replacing:");
System.out.println("str1: "+str1 +"\nstr2:" + str2);
}
}
Output
Strings before replacing:
str1: www.includehelp.com
str2:Hello World!
Strings after replacing:
str1: Hello World!
str2:Hello World!
Consider the program:
Here, we have two strings str1 and str2, str2 will be replaced with str1 and finally, str1 is the replaced string (which will be returned through the function).
