Please help with Java!

Given the following code fragment: String name = "programming"; evaluate name.index0f(' m ') Answer: Consider the following class definition: In the following client code, is the object that w references mutable or immutable? Widget w= new Widget (5); a. it is immutable b. it is both mutable and immutable c. it is mutable d. it is neither mutable nor immutable Consider the following Java code fragment: String text = "ABC/DEF/GHI/JKL"; var tokens = new java.util.StringTokenizer(text, "/"); while (tokens.hasMoreTokens ()) \{ System.out.println(tokens. nextToken()); \} What is the second line this code fragment prints? a. JKL b. GHI c. DEF d. ABC e. / Consider the following class definition: public class Widget \{ private int value; public Widget(int val) value = val; \} public int get ()\{ return value; \} public void set (int n){ value =n; \} After the following client code executes: Widget w1= new Widget(5); Widget w2= new Widget (20);//A. w2=w1 what happens to the widget object created at the line labeled A ? a. it results in a memory leak unless the programmer adds the code to deallocate the object b. nothing c. it is eligible for garbage collection If the use of a Random object is limited to a single method, it is best to make the Random reference local to that method. Select one: True False Position the code pieces correctly to make the Java statement that would assign to the variable x the result of computing 5. =(1); Consider the following class definition: public class Widget \{ private int value; public Widget(int val) \{ value = val; \} public int get ()\{ return value; \} In the following client code, is the object that w references mutable or immutable? Widget w= new Widget (5); a. it is mutable b. it is neither mutable nor immutable c. it is immutable d. it is both mutable and immutable
