> 1. convert between data types

//convert integer to string
int x=0;
String s=String.valueOf(x);

> 2. use an array

//init an array with numbers 0-9
int a[10];
for(int i=0;i<10;i++) {
 a[i]=i;
}

> 3. use a vector

//create a Vector and add integer values 0 and 1 to it (as instances of
Integer class)
java.util.Vector v=new java.util.Vector();
v.add(new Integer(0));
v.add(new Integer(1));

> 4. use a loop

see case [2] above

> 5. use branching statement

int x=1;
if (x!=0) {
 System.out.println("value is "+x);
 //if the above line doesn't compile try "value is "+String.valueOf(x)
instead
} else {
 System.out.prinltn("value is zero");
}

to make all these into a program do something like

public static void main(String[] args){
 //...put your code here, using "System.out.prinltn(...)" wherever you need
to print out messages/values
}
