public class Test {    public void  m1(String arg1)  {        arg1="Test";    } public static void main(String[] args) {        Test test1= new Test();        String s= "Hello";        test1.m1(s);        System.out.println(s);  }}

Analyze the following code carefully. Please select the one that applies.public class Test {  public static void main(String[] args) {    A a = new A();    a.print();  }}class A {  String s;  A(String s) {    this.s = s;  }void print() {    System.out.println(s);  }}

public class testmeth{static int i = 1;public static void main(String args[]){System.out.println(i+” , “);m(i);System.out.println(i);}public void m(int i){i += 2;}}

public class Main { public static void main(String args[]) { System.out.print("Hello World "); System.out.println("Hello Know Program"); }}

public class Code { public static void main(String[] args) { method(null); } public static void method(Object o) { System.out.println("Object method"); } public static void method(String s) { System.out.println("String method"); }}

Consider the given code: class String_demo { public static void main(String args[]) { char arr[] = {'Q','W','E','R','T','Y}; } }Which among the following option will print QWERTYA) System.out.println(arr);B) System.out.println(arr.toString());C) new String(arr); System.out.println(str);D) System.out.println(Arrays.toString(arr));
