Thread: Constructing Strings

Hello,

This probably seems simple, well I'm sure all of mine seem simple, so here it goes. I am having trouble constructing strings. str1, str3, and str4 give pre-compile errors and show up yellow in my IDE. The pre-compile errors are commented in the code below. str2 gives a pre-compile error (commented in code below) and also a runtime error. The runtime error was:
Exception in thread "main" java.lang.RuntimeException: Uncompilable source code - Erroneous tree type: <any>
at hsstringdemo.HSStringDemo.main(HSStringDemo.java:1 4)

Line 14 is where the string is declared and initialized, which I think is also called the string constructor.

I imported java.lang.Object and java.lang.String in hopes that something was not defined, but to no avail. I tried using the code tags this time, seems simple, but tell me how I am doing.

package hsstringdemo;
import java.lang.Object;
import java.lang.String;
 
public class HSStringDemo {
    public static void main(String[] args) {
        // Declare strings in various ways.
        String str1 = new String("Java strings are objects."); //Pre-Compile Error: String constructor invocation
        String str2 = new "They are constructed in various ways."; //Pre-Compile Error: <identifier> expected
        String str3 = new String(str1); //Pre-Compile Error: String constructor invocation
        String str4 = new String(str1 + str3); //Pre-Compile Error: String constructor invocation
 
        System.out.println(str1);
        System.out.println(str2);
        System.out.println(str3);
        System.out.println(str4);
 
    }
}

Thank you everyone for the information.

Your a little late with your answer. The question was asked a month ago.
