Thread: Choice condition IF based on value

How come I can't get into the else? where did I go wrong? I would like to do this test based on this structure that I have outlined.
I don't want to use switches and other things.
Only with this structure.

public static void main(String[] args) {
		String a = "10";
		String b = "6";
		boolean t = false;
		boolean v = false;
 
		for (int i = 0; i < a.length(); i++) {
			for (int j = 0; j < b.length(); j++) {
				if (a.equals(b)) {
					t = true;
					System.out.println("sono uguali");
				}
			}
			if (t == false) {
				if(a != b) {
				System.out.println("non sono uguali: " + a + "!=" + b);
				}
				else {
					v= true;
					if(a.equals("10")) {
						System.out.println("Non inserire il numero 10");
					}
				}
 
			} 
		}
	}

suppose that a and b are objects, does this approach work the same?

public static void main(String[] args) {
		String a = new String();
		String b = new String();
		boolean t = false;
		boolean v = false;
		a = "10";
		b = "7";
 
		for (int i = 0; i < a.length(); i++) {
			for (int j = 0; j < b.length(); j++) {
				if (a.equals(b)) {
					t = true;
					System.out.println("sono uguali");
				}
			}
			if (t == false) {
				if (a != b) {
					System.out.println("non sono uguali: " + a + "!=" + b);
				} else {
					if (a.equals("10")) {
						v = true;
						System.out.println("Should not be  10");
					}
 
				}
 
			}
 
		}
	}
 
}

does not enter me

if (a.equals("10")) {
v = true;
System.out.println("Should not be 10");
}



suppose there is get and set does it work the same?

can't get into the else

You won't enter the else unless the if is false.

if (a != b) {

Always use the equals method when comparing objects like Strings.
