如何在java中处理使用同一对象的多个if语句和case？

if (condition1) {
    // 处理条件1的逻辑
} else if (condition2) {
    // 处理条件2的逻辑
} else if (condition3) {
    // 处理条件3的逻辑
} else {
    // 处理其他情况的逻辑
}

switch (condition) {
    case value1:
        // 处理条件1的逻辑
        break;
    case value2:
        // 处理条件2的逻辑
        break;
    case value3:
        // 处理条件3的逻辑
        break;
    default:
        // 处理其他情况的逻辑
        break;
}

public interface Strategy {
    void execute();
}

public class Strategy1 implements Strategy {
    @Override
    public void execute() {
        // 处理条件1的逻辑
    }
}

public class Strategy2 implements Strategy {
    @Override
    public void execute() {
        // 处理条件2的逻辑
    }
}

public class Strategy3 implements Strategy {
    @Override
    public void execute() {
        // 处理条件3的逻辑
    }
}

public class Context {
    private Strategy strategy;

    public Context(Strategy strategy) {
        this.strategy = strategy;
    }

    public void executeStrategy() {
        strategy.execute();
    }
}

// 使用示例
Context context;
if (condition1) {
    context = new Context(new Strategy1());
} else if (condition2) {
    context = new Context(new Strategy2());
} else if (condition3) {
    context = new Context(new Strategy3());
} else {
    // 处理其他情况的逻辑
}
context.executeStrategy();
