I have a compilation problem in a Java program:
class FigureEditor {
int[] a; ----- Syntax error on token ";", , expected
a = new int[5];
}
What am I doing wrong?

You can't have "floating" statements in the class body.
Either initialize it directly:
int[] a = new int[5];
Or use an initializer block:
int[] a;
{
a = new int[5];
}

so, do i have to put everything in {}? for example { a[0] = 3124; } ?

generally, you have to put things in methods. Initialization can happen together with the field, in a block, or in a constructor. But that's just initialization, not "everything"
class FigureEditor
{
int[] a = new int[5];
}
You can't use variables outside a method.

How its possible? you have to initialize the int[] a any of 1 following ways,
Possible ways:
class FigureEditor {
int[] a; {
a = new int[5];
}
}
Or
class FigureEditor {
int[] a = new int[5];
}
Or
class FigureEditor {
int[] a;
public FigureEditor() {
a = new int[5];
}
}
