Consider the following classes:
public class First {
public void method2() {
System. out. println("First2");
}
public void method3() {
method2();
}
}
public class Second extends First {
public void method2() {
System. out. println("Second2");
}
}
public class Third extends Second {
public void method1() {
System. out. println("Third1");
super. method2();
}
public void method2() {
System. out. println("Third2");
}
}
public class Fourth extends First {
public void method1() {
System. out. println("Fourth1");
}
public void method2() {
System. out. println("Fourth2");
}
}
Suppose the following variables are defined:
First var1 = new Second();
First var2 = new Third();
First var3 = new Fourth();
Second var4 = new Third();
Object var5 = new Fourth();
Object var6 = new Second();
Indicate below the output that would be produced by each statement shown. If the statement produces more than one line of output, indicate the line breaks with slashes as in a/b/c to indicate three lines of output with a followed by b followed by c. If the statement causes an error, write the word error to indicate this.
var1.method2();
var2.method2();
var3.method2();
var4.method2();
var5.method2();
var6.method2();
var1.method3();
var2.method3();
var3.method3();
var4.method3();
var5.method3();
var6.method3();
((Second) var4).method1();
((Third) var4).method1();
((Second) var5).method2();
((First) var5).method3();
((Third) var5).method1();
((First) var6).method3();
((Second) var6).method1();
((Second) var6).method3();
