Can you explain what you are trying to do and post some code to help us understand what your problem is?

i want to make a method that adds a JButton to a Tabbed Pane so i don't have to do this:
Code:
panel1.add(Tabs.r1);
panel1.add(Tabs.r2);
panel2.add(Tabs.r3);
panel2.add(Tabs.r4);
panel2.add(Tabs.r5);
panel2.add(t3);
panel2.add(bedrock);
panel2.add(stone);
panel2.add(dirt);
panel2.add(grass);
panel2.add(log);
panel2.add(planks);
panel2.add(tnt);
panel2.add(stonebrick);
panel2.add(netherbrick);
panel3.add(t2);
panel4.add(bb1);
panel4.add(bb2);
panel4.add(bb3);
panel4.add(b4);
panel4.add(b5);
panel4.add(b6);
panel4.add(b7);
panel4.add(b8);
panel4.add(b9);
panel4.add(bedrock);
panel4.add(stone);
panel4.add(dirt);
panel4.add(grass);
panel4.add(log);
panel4.add(planks);
panel4.add(tnt);
panel4.add(chest);
panel4.add(stonebrick);
panel4.add(netherbrick);
panel4.add(wool);
panel4.add(gravel);
JComponent cobble = addNewButton("test","test");
panel4.add(cobble);
panel5.add(gens);
window.add(p1);
window.add(l1);
window.add(type);
p1.add(next);
p1.add(back);
window.add(button);
p1.add(menu);
window.add(b1);
window.add(b2);
window.add(b3);
p1.add(l2);
window.add(Crafting.craft1);
window.add(Crafting.generator);
window.add(Crafting.methods);
window.add(Item.items1);
window.add(Block.blocks1);
window.add(Crafting.tp1);
window.add(load);
window.add(Crafting.t1);
bg.add(Tabs.r1);
bg.add(Tabs.r2);
bg2.add(Tabs.r3);
bg2.add(Tabs.r4);
bg2.add(Tabs.r5);
addtowin();
firstpage();
t3.setVisible(false);
then i want to be able to set if the buttons should be visible or not without writing out every button because that is going to be a HUGE pain
Code:
ButtonTest.bedrock.setVisible(true);
ButtonTest.stone.setVisible(true);
ButtonTest.dirt.setVisible(true);
ButtonTest.grass.setVisible(true);
ButtonTest.log.setVisible(true);
ButtonTest.planks.setVisible(true);
ButtonTest.type.setVisible(false);
ButtonTest.l2.setVisible(false);
ButtonTest.bb1.setVisible(false);
ButtonTest.bb2.setVisible(false);
ButtonTest.bb3.setVisible(false);
ButtonTest.b4.setVisible(false);
ButtonTest.b5.setVisible(false);
ButtonTest.b6.setVisible(false);
ButtonTest.b7.setVisible(false);
ButtonTest.b8.setVisible(false);
ButtonTest.b9.setVisible(false);
ButtonTest.tnt.setVisible(true);
ButtonTest.chest.setVisible(true);
ButtonTest.stonebrick.setVisible(true);
ButtonTest.netherbrick.setVisible(true);
ButtonTest.wool.setVisible(true);
ButtonTest.gravel.setVisible(true);
ButtonTest.b.setVisible(true);
isTrue = true;
after that i want to be able to set the action without typing out this(i want it to be one line):
Code:
public void actionPerformed(ActionEvent p)
{
if("b1".equals(p.getActionCommand()))
{
List.True();
b1 = true;
}
if("b2".equals(p.getActionCommand()))
{
List.True();
b2 = true;
}
if("b3".equals(p.getActionCommand()))
{
List.True();
b3 = true;
}
if("b4".equals(p.getActionCommand()))
{
List.True();
b4 = true;
}
if("b5".equals(p.getActionCommand()))
{
List.True();
b5 = true;
}
if("b6".equals(p.getActionCommand()))
{
List.True();
b6 = true;
}
if("b7".equals(p.getActionCommand()))
{
List.True();
b7 = true;
}
if("b8".equals(p.getActionCommand()))
{
List.True();
b8 = true;
}
if("b9".equals(p.getActionCommand()))
{
List.True();
b9 = true;
}
if("bedrock".equals(p.getActionCommand()))
{
new Recipe("Block.bedrock");
done();
List.backto();
}
if("stone".equals(p.getActionCommand()))
{
new Recipe("Block.stone");
done();
List.backto();
}
if("dirt".equals(p.getActionCommand()))
{
new Recipe("Block.dirt");
done();
List.backto();
}
if("grass".equals(p.getActionCommand()))
{
new Recipe("Block.grass");
done();
List.backto();
}
if("log".equals(p.getActionCommand()))
{
new Recipe("Block.log");
done();
List.backto();
}
if("planks".equals(p.getActionCommand()))
{
new Recipe("Block.planks");
done();
List.backto();
}
if("tnt".equals(p.getActionCommand()))
{
new Recipe("Block.TNT");
done();
List.backto();
}
if("stonebrick".equals(p.getActionCommand()))
{
new Recipe("Block.stoneBrick");
done();
List.backto();
}
if("netherbrick".equals(p.getActionCommand()))
{
new Recipe("Block.netherBrick");
done();
List.backto();
}
if("chest".equals(p.getActionCommand()))
{
new Recipe("Block.chest");
done();
List.backto();
}
if("brick".equals(p.getActionCommand()))
{
new Recipe("Block.brick");
done();
List.backto();
}
if("wool".equals(p.getActionCommand()))
{
new Recipe("Block.cloth");
done();
List.backto();
}
if("gravel".equals(p.getActionCommand()))
{
new Recipe("Block.gravel");
done();
List.backto();
}

One way to reduce the number of lines is to put the component references into an array:
stone, dirt, grass, etc And then use a loop as shown above to get the references and call the method.
It will take several statements: loop and if test.
Put the Strings: "b1", "b2", etc in an array and use a loop through that array to compare its elements with the String returned by the getActionCommand() method.
Because there are different statements in the if, there will have to be different loops for each set of statements.
One for when setting true and one for setting false.

If you want to call the same method on all the buttons,
Try putting references to the buttons into an array and write a loop to index through the elements in the array and call the method for each element in the array.

I suggested doing 3 things. Which one are you having problems with?
1) define an array
2) write a for loop
3) use array's elements to call method
I gave sample code in post #10

Just declare a static array of JButton type, then add all button instances you created into this array right after the initialisation block (the block which instantiates all the JButton instances in your program with the keyword new ), and loop through these JButton instances one-by-one using a loop, in which you invoke the method(s) you want (them all) to be invoked whenever it is necessary to invoke the same method(s) on all JButton instances anywhere in the codes. It is just that simple.
