Scanner in =new Scanner(System.in);
int l1=in.nextInt();
int l2=in.nextInt();
int l3=in.nextInt();
int l4=in.nextInt();
int L=l1;
int angle=in.nextInt();
if((l1==L)&&(l2==L)&&(l3==L)&&(l4==L))
{
if(angle==90)
System.out.println("SQUARE");
}

I want to convert GBP 29.15* to just 29.15.
Can anyone please help?
I have already tried parsing to integer/float, substring etc. but getting an error.
Try this:
float f = Float.valueOf("GBP 29.15*".replaceAll("[^\\d.]+|\\.(?!\\d)", ""));
It removes all non-number characters and then finds the float value.

int [ ] a;
What is happening in this line can anybody describe. It has spaces between [].
You are defining a reference to an array which is presently null, and therefore of undefined size.
This is correct syntax. The spaces in between square brackets are not relevant.
Here is some proper further usage:
int [] a = new int[10];
