Demonstrates the VARARGS feature of java for variable arguments along with normal parameters.
Here we demonstrate how we can pass normal parameter along with varible arguments.
class VarExample
{ public void Test(String str, int ... arr)
{System.out.print(str + arr.length + "contents ");
for(int i : arr){
System.out.print(i+" ");}
System.out.println();
}
public static void main(String a[])
{VarExample ve =new VarExample();
ve.Test("First argument",1);
ve.Test("Second argument", 11, 12,13);
ve.Test(" No variable arguments ");
}
}
Demonstrates the VARARGS feature of java for variable arguments.
This example shows how to use VARAGRS feature of java for variable length arguments instead of using array.
class VarExample
{
public void test(int ... arr)
{
System.out.print("No. of arguments "+arr.length+"contents ");
for(int i: arr)
{ System.out.print( i+ " ");
}
System.out.println();
}
public static void main(String a[])
{ VarExample ve= new varExample() ;
va.Test(10);
va.Test(11,12,13,14);
va.Test();
}
}
Variable length argument implemented using array.
This Example demonstrates how we can pass variable argument using array, but this approach is old. Now a days we use Varargs feature included in J2SE 5.
class VariableArr{
public void Test(int[] arr)
{ System.out.println("No. of args "+arr.length+"contents ");
for(int i : arr)
{ System.out.print( i+" ");
}
System.out.println();
}
public static void main(String a[])
{ VariableArr va= nw VariableArr();
int a[]= {20};
int b[]={2,4,6};
int c[]= {};
va.test(a);
va.test(b);
va.test(c);
}
}
